My current system:
Athlon 800 (200 bus)
A7V
256MB SDRAM-133
ASUS V7100 GF2MX 32MB AGP
Creative Labs SB-Live! Value
Samsung 17 inch 755DF
I currently use FSO in HTL with Glow, Spec, and jpgtga, although I've taken to only extracting some of the tga effects (not the nebulas) and I use Lighty's updated V2 planet pack though with the 3 larger planets relpaced by the DDS versions. I used to fly with all the bells and whisles on, but it would often slow my framerate to a chug, chug, chug 4 fps. The key seems to be in the shinemaps. Without shinemaps I can fly at a reasonable framerate (for me... usualy between 30 & 50 unless there's too much action). If anyone is gonna use the shinemaps and the environment map stuff (once it becomes an official feature), then the min. system requirements should be bumped up to the reccommended specs.

I't be cool if we had a little piece of software for the eventual more large scale release of the SCP. During initial setup of say FSO-4.0 (by that point perhaps) and all the media for it, there would be a popup that says "for those who aren't good at computers, we reccommend running this little porgram that will examine the critical specs of your computer and reccommend what features you should or shouldn't install for the best gameplay vs. eye-candy ratio." OK, maybe by 3.8, but it would still go one step closer to user friendlyness than the Launcher currently is. Don't get me wrong, the Launcher is a great improvement over what we had before, and it is still WIP, so this is not meant as any kind of put-down, but there are features (particularily in the command line flags) that say "use this for better eye-candy" or "this will speed things up", but the launcher doesn't know if someone has a system like mine, or a Killer Gaming Rig. Something to fill this gap needs to be in place when the SCP makes its more public launch sometime in the future.
