I recently decided to replay Blue Planet with the latest builds and having freshly reinstalled everything. But I've got a bit of an issue, the game slows to a crawl (hell, slower than a crawl) during cutscenes or when I'm in third person during a mission. The game runs great in first person however. I've done a bit of troubleshooting and disabling GLSL support has everything running flawlessly.

My second problem is having shadows enabled causes any ship entering or exiting subspace to simply, well, not exist. They're invisible aside from their running lights. I know shadows are probably buggy in general but I'm wondering if there's maybe some way to fix this?

I've tried playing with both the AVX and SSE2 builds but I doubt that would matter as this is a video issue.

I should also say I'm running on an AMD HD7770 which while not the best card by any stretch of the imagination shouldn't have issues running the game. I've also tried running both the latest stable and beta drivers for my card to no success.

1) Please post your fs2_open.log file.  Instructions on how to do this can be found in this post.

2) Can you reproduce any of this with trunk builds, or is it specific to BP builds ?

This is an issue with GPUs based on AMDs' GCN architecture and current drivers; I have so far been unable to actually determine the cause as AMD's dev tools still need some work before they're usable again.

Went ahead and ran Icarus for the log file.(The file seems a tad large and messy, so I attached it. Apologies if I did something wrong here) Performance drops throughout the whole cutscene. I haven't been able to reproduce the issue outside the War in Heaven campaigns or on other builds like 3.7.0 or even some of the latest nightly builds running the vanilla campaign.

Shame about the shadows, thanks for clearing that up. Guess I'll just have to live with temporarily invisible ships.

There is a driver version out there that clears up the slowdown during cutscenes, I'll tell you which one once I get home again.

[leoben]

The E meant the stuttering problem is GCN related. 7770 is GCN based.

I've asked our driver and dev teams to look at this.

BTW the issue you see has some randomness attached to it. Did you notice how the issue goes away if you use the afterburner on your ship?

[Goblix]

Ah. Yeah the framerate smooths out when I use afterburners. That's really strange.

Just an FYI, for large logs, you can either attach them (as you did), or post them within [code]  <paste log / code here> [/code] tags, which will put the contents of the log within a code box like this:

“Good Morning!" said Bilbo, and he meant it. The sun was shining, and the grass was very green. But Gandalf looked at him from under long bushy eyebrows that stuck out further than the brim of his shady hat.

"What do you mean?" he said. "Do you wish me a good morning, or mean that it is a good morning whether I want it or not; or that you feel good this morning; or that it is a morning to be good on?"

"All of them at once." said Bilbo. "And a very fine morning for a pipe of tobacco out of doors, into the bargain.
 Either is acceptable; it's up to your preference.

I'm getting the stuttering issue in both third and first person while playing on a 7850. Have there been any developments on this issue?

[The E]

Download this, and unpack it in your fs2 directory. It's the atioglxx.dll from the 13.03 Catalyst driver, which seems to work properly.

[Mr. Vega]

That solved the stuttering. But it also produced the attached glitch. In game it only appears when the ship surface is reflecting a strong or very close light source. Something with specular? I'm using catalyst 13.12 (yes, I know I might just have to revert everything back to 13.1 to be able to play this).

that's looking pretty acataleptic

Hmm, interesting.

That may give me a good hint of where to look in the shader code for an answer to that issue. Thanks for that tip.
