Re: Crysis demo available!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
From what I have read so far DX10 users don't have the problems with performance as DX9 users have. At least that is my impression from different forums I have read. That is quite sad.

I also noticed that the game runs smoother for me when I extract all the graphic and soundfiles. You can find these files in the game folder in your crysis directory. Use 7z to extract them in folders with the same name of the file and then move these files out of the crysis folder. Also installing the lastest nvidia beta drivers helped...well less in crysis but all other games are running better now ^_^

Re: Crysis demo available!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Really? Well I'm still using old drivers and it runs quite well at least better than I expected with about 20-35 fps at 1280x1024. It becomes a bit choppy in heavy firefights but is still quite fluid. I am using an X2 3800 2,0 GHZ and an 7800GTX together with 2GB RAM. Textures are on High the rest is on Medium.

Re: Crysis demo available!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
No framerate issues here even at 1920x1200 with all settings at Very High (8800GTX/6600/2GB Ram/ Vista).  The C-17 cutscene at the beginning was a bit choppy here and there, but that's all I noticed.  I can't wait for the full release now.

Same here, minus 'very high' and Vista. Looks beautiful on my LP3065, although I'll need another 8800GTX to run it at its native 2560*1600 res. And no load screens or caching jerkiness either - that's some seriously clever design there.

Has anyone managed to avoid the Korean frigate's missiles and take a peek at it yet?

Why? Most DX10 games have had support added in as an afterthought with a couple of token graphical features. Crysis has had DX10 support since before Vista was released, IIRC.

Re: Crysis demo available!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
This might help those of you with specific hardware types such as 64-bit processor(s), multiple (SLi, CrossFire) GPUs, or Windows Vista:

Quote from: readme
==================================================================
Optimizing Graphical Performance
==================================================================

For a good gameplay experience you generally want to have a fast
and stable frame rate. Additionally, it's good to have quick
response on user input.

Crysis is made for high image quality and runs best with a
powerful main processor, a lot of main memory, and a powerful
graphics card with a lot of video memory. The performance can be
limited by one or more of the above mentioned points. By default
the game prefers settings for better performance which means
many options in the menu go to low quality mode. However if
hardware allows, this can be changed by the user. By adjusting
graphical settings you can find a good compromise for your
computer. Some very high quality features can only be accessed
when running on DirectX 10 which requires Windows Vista. Features
which are not accessible appear grayed out.

It is advisable to have the latest graphic card drivers as the
hardware vendors often include optimizations for specific games
into their drivers. Some graphics card settings in the Windows
display settings can affect performance or quality.
Windows Vista is a bit more demanding on hardware side and drivers
can be less optimized. This makes it even more necessary to get
recent drivers and hardware running well on Vista. Memory
management within Windows Vista has changed a bit which makes it
more memory demanding. Microsoft released a patch to improve this
situation. More details and the download can be found there:

    http://support.microsoft.com/kb/940105

Modern processors now support 64bit which mostly improves their
memory managing capabilities. This feature is only available if
the operating system support 64bits. As Crysis is demanding in its
memory requirements it can benefit from a 64bit OS. On a 64bit system
the engine texture streaming can be disabled as the operating
system can handle all data in a level. 64bit also supports more
main memory available for each application. Both are beneficial and
can result in improved frame rate and frame rate stability.

Multiple processors allow processing of some tasks in parallel which
mostly improves computational heavy situations like explosions.
The game utilizes multiple processors automatically.

Some hardware vendors have solutions to utilize multiple graphic
cards in parallel (e.g. Crossfire or SLI) and that can greatly improve
render performance. This requires the engine to run in the
"MultiGPU" mode. The speedup depends on the scene and system
properties like the main processor performance. Frame rate can be
less stable but is often much higher.

The screen resolution is one of the most critical options for
performance and quality. For best quality on a TFT it's best to
pick a resolution which fits the hardware resolution (check your
monitor manual). Generally a higher resolution gives better
quality but requires more memory and renders slower. However, this
depends on the hardware configuration and sometimes increasing the
resolutions does not even affect performance.

Crysis features soft real-time shadows which play an important
role in the image look. Shadows can be activated and deactivated
in the advanced options menu.

Crysis also features HDR rendering which can be activated via the
shading quality in the advanced options menu. In HDR mode you can
notice bright image areas not appearing burned out. You can also
notice the eye adapting to the brightness of the environment.
Deactivating HDR can give you higher frame rates as it requires
more graphics card performance and graphics card memory.

Anti aliasing is a hardware feature to improve image quality.
Edges become softer and lower resolutions can look quite
acceptable. The hardware feature works for most engine techniques
but some graphical features like atmospheric effects may appear
slightly different.

If your graphics card supports multiple monitors you might not get
full 3D acceleration on each display. This can be avoided by only
activating one display in the driver control panel.

To get a stable frame rate you should make sure your computer is
not busy with other tasks such as virus scans or downloading files.

Vertical Sync is a graphical option you can choose in your graphics
card driver. Switching this option off gives you best frame rate
but the image quality might suffer and the image may appear torn
apart. This is mostly noticeable when doing a quick horizontal
camera rotation. For benchmarking, this option is usually switched
off.

Modern TFT monitors have short response times and other features
which help when the eye is following fast paced action.

Input devices need to submit their data in some rate and with a
better connection (serial, PS2, USB) or better hardware you can
get a faster rate. This can result in improved response time and
an improved game experience.

Re: Crysis demo available!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Well I downloaded and installed the demo yesterday and I'm having some serious graphics corruption problems...

The menu system is fine but as soon as I get to in-game graphics I'm faced with a real mess. Flickering box-like textures and - as near as I can tell - models where only the eyeballs are actually showing and the rest seems invisible. It's a mess.

Does anyone else have this problem and any suggestions for a fix? I'm running the game with all graphics options in Low except Textures and Models which I set to Medium. And these specs...

GeForce 7600GT
ForceWare Version: 163.71
AMD 3500+ CPU
2GB PC2100 DDR Memory
DirectX 9.0c
Windows XP SP2
SB Audigy2 ZS

EDIT: Solved my own problem. It seems that regardless of all the other details, Shaders have to be on high or else I get graphics corruption. It seems to be running fine - if slowly - now.

I've seen the comments going both ways. It's hard to tell for sure at this point. As far as the IQ goes, it's apparently possible to get most of the DX10 visual features in DX9 mode through some simple tweaks, although with lower performance.

To be honest though, I don't put much stock into any purely qualitative comments that people post about performance in games. I'm seeing plenty of people getting 30fps averages (which means it would drop to about 15 in heavy fights) in this demo on other forums and calling that very playable, smooth, flawless, etc. :p

That is precisely the problem. Everyone has a totally different idea of what playable means, so such comments are meaningless if they aren't backed by any numbers. Any framerate is playable as long as you're used to it. I used to play an old racing game called Vette on my Mac many years ago that always ran at 2-5fps, which I found great back then, while I rarely tolerate drops below 50 or so in FPSs these days (unless they're very intermittent) and turn down settings if they persist. And that is leaving aside the difference between "playable" and something like "flawless," the latter seemingly indicating that the movement appears indistinguishable from motion in real life to the person.

Re: Crysis demo available!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
You are right. I have played a lot of the Unreal demo before Crysis and Unreal is fast...hell I sometime wish its slower ^_^
Still I tweaked around with my drivers and found a default setting for crysis in the Nvidia drivers. Selected it and now I turn everything high and get a good gameplay feeling. Since I am more the sneeking guy that loves to snipe I don't get into fights so drops in frames aren't suspected.
Has anyone managed to get through the demo without killing anyone?

One point that should be taken into account is that this demo is a pre-release demo that so its room for improvements.

Still a very nice game (graphic and gameplaywise) and when you stand at the top and look over the island it makes a great screensaver. ^_^

PS: At the SCP guys...how long do you think it takes you to give FS2 all these nice gimics like motion blur and bloom/HDR ^_^

Re: Crysis demo available!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Everything above 30FPS is playable, since the human eye can't tell the diferene between 1000 FPS and 30FPS anyway.

I think a static bloom effect will probably make it into the game soon after the shader system is complete. That alone would improve the graphics a lot as long as it's not overdone.

The human eye (if I remember correctly) can usually see 24 frames per second.

60 fps used to be the lowest playable speed (30 vertical frames, 30 horizontal frames).

<EDIT>

There's no real difference in terms of speed between 60 fps on older games and 30 fps on newer ones.

That's very odd... take a look at my system specs.. everything runs flawlessly with all settings on low.  I'll post what ForceWare I'm using when I find out... but I did *not* update for Crysis, as I heard it caused a problem with FS or something.

For one thing, the human eye is an analog device that has no internal limit on how fast it can input data. How fast the brain can interpret that information depends on a number of other factors and varies a lot between people as well as the types of images seen. I can make out subtle differences up to about 120fps in most FPS games on an appropriate display, and I dare say that most of the people I see claiming these low numbers as strict limits can see flickering on a 60hz CRT and therefore at least 60fps. :p

As for the rest of that post, all I can say is :wtf:.

Actually, 24 fps is about at the limits between a slideshow and something that is actually recognized as moving picture by the visual cortex.

As CP said, eyes actually send input a lot faster than 24 images to the brain being analog devices; it's the visual cortex that either discerns the signals as a series of images, or a smoothly moving picture. In fact, eyes don't send "frames" to the visual cortex, they are more like continuously updating the changes in what they receive and what is projected to the visual cortex matrix [in case you didn't know, the area where the visual nerves end in the brains is actually shaped like the projection of the field of vision, so different parts of retina connect to corresponding physical location on the visual cortex - now how's that about interesting stuff], and as you might know, different parts of retina have different abilities. The edges with rod cells have a relatively fast response time as well as sensitivity to small amounts of light, and that's why they are well suited at seeing fast movements as well as vibrations (which are pretty much the same thing anyway as far as the eye is concerned). The center with biggest concentration of photoreceptor cells, most being cone cells which give us RGB colour vision but they are consequently less sensitive to minimal amounts of light and also have somewhat longer response time.

And actually, the accurate center part of the vision is responsible for sharp vision for almost all of the field of our vision; our eyes continuously move very fast to different parts of the field of vision, sending accurate vision updates for the visual cortex, which fools our conscious perception to think that all of our vision is as accurate as the center part. You can try this out if you can concentrate long enough - keep staring at some point and try to move your eyes as little as possible. After a minute or so, the edges of the field of vision start becoming fuzzier and fuzzier, as the visual cortex starts to forget about the surrounding stuff in lack of accurate updates. In the end you might be able to see how inaccurate the edges of our vision actually are compared to the "yellow spot" in the middle of the retina.

Ehmmm, where was I.

24 fps is, as said, slightly above the limits of what the brain starts to interpret as a movie instead of a bunch of consequential images. Of course, there are also other factors that affect the interpretation, such as how fast the movement in the movie is across the screen and so forth. For example, an object moving across the screen in one second with 24 fps will move 1/24th of the screen between the frames, and that's definitely gonna show as stuttering image and might even break the illusion of a moving image.

I can pretty much always see the 60Hz flicker in most tube TV's before they warm up properly, and even afterwards it's usually visible, just not prominent.

And at movies I'm pretty much constantly annoyed by the low FPS which causes frames to appear jumpy any time when the camera is panning or characters/stuff move across the screen as I said.


Oh, and the demo seems to work pretty well on 1024x768 with all settings on low, and I have AMD64 3200+, 3GB DDR-SDRAM and a factory overclocked 7600GT. Haven't tried to increase any settings yet, might be interesting to experiment which of the settings have the most impact. Also, it feels pretty playable although the weapons feel horribly inaccurate, even in aimsight mode. :rolleyes:

Re: Crysis demo available!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Ya, I do notice a lot more eye strain on 60 Hz... which is why it's recommended you set it as high as its allowed (mine is set at 75 Hz)... although, I hear on flat panels, the eye strain doesn't occur?  :confused:

Yeah, on TFT/LCD (and plasma?) screens the familiar frequency flashing of tube tellies is not there, due to the difference in how the image is generated.

In colour tube screens, there's a surface coated with three kinds of fluorescent matter which glows in red, green or blue when it's hit by electrons. And the electron beam produced in the tube is swept to cover the whole fluorescent panel as many times in second as the refresh rate allows, usually 60 times per second with televisions and most often more with computer screens - usually at least 75, sometimes as high as 100 or more but those are more expensive AFAIK... Anyway, this mechanism means that every "pixel", or location, on the fluorescent panel flashes on and off about 60 times per second if it's not black in the image.

Basically the television screen works almost exactly like an oscilloscope, to a degree that it would be theoretically possible to use oscilloscope as a BW television screen and vice versa... :p

On flat panels, the light is produced by steadily glowing lights on the background of the liquid crystal display, and the panel's pixels don't flash on and off every time their state is updated by the signal, thus reducing the eye strain and makign static image much easier to look at even at 60 Hz frequency.

I dunno the exact mechanism of plasma screens but I would imagine that there's a steady source of light as well instead of swooping electron beam of the tube screens.

Flat screens, however, have other problems like slower response time and lagging images, because the LCD display's pixels have limitations on how fast they can change from one state to other, and the other thing is that LCD displays have usually worse colour and contrast range compared to good tubes. Which means that in pro graphics, the tubes are still AFAIK preferred over flat screens; the major advantage the flat screens have over tubes is that they are physically more manageable and they suit better for office work because of the aforementioned reduced eye strain.
