(RESOLVED) Penumbra Performance Problems? - MercenaryForHire - 04-09-2007 RESOLVED Installing the older NVIDIA 80-series drivers fixed the performance issues. Other users of the 90-series should try downgrading to see if this resolves their problems. Penumbra's performance seems to be schizophrenic at times. http://frictionalgames.com/forum/attachment.php?aid=214 This is at 640x480, all graphical options off, Very Low shaders. Basically Quake 1, and that's being generous. I'm getting a whopping 4fps in this screenshot. Now, you might think that my system is just hosed. Well, check this one out. http://frictionalgames.com/forum/attachment.php?aid=216 1280x1024, everything on except Motion Blur, AA, and AF. And this is getting 30fps. With the flashlight on, which is an extra demand on the graphics card. Now, take a look at this. [attachment=220] Same high detail, but lowered to 800x600. (I was experimenting.) If I look at that map directly, I get 60fps. If I turn to the left about 45 degrees, I get about 40fps. However, if I turn 90 degrees to the left, and look into a dead end, I get less than 10fps. There is nothing to render. Why is performance so horrid? I'm reinstalling the tech demo to see if that runs horribly too. RE: Penumbra Performance Problems? - MercenaryForHire - 04-09-2007 [attachment=221] The tech demo ran like butter. All the eyecandy, including Motion Blur and 4xAF, and the lowest I ever saw was 18fps or so (not counting the sequence in the elevator) - most of the time was north of 30fps, and plenty of times at 60. RE: Penumbra Performance Problems? - Dark - 04-09-2007 this is indeed strange what are your system specs? are you running vista?(since alot of performance problems ocure when tunning vista) RE: Penumbra Performance Problems? - Thaliur - 04-09-2007 This could be connected to Anisotropic filtering. When you look into that "dead end", you'll have a lot of textures at a steep angle to your point of view, and AF has a lot of work to do.

It's not a scorcher, but it has no problems with other OpenGL based games (Doom 3, Quake 4, PREY) and it's defintely head and shoulders above the "minimum requirements" for Penumbra. RE: Penumbra Performance Problems? - MercenaryForHire - 04-09-2007 Thaliur Wrote:This could be connected to Anisotropic filtering. AF has never been enabled in anything but the tech demo; but good thought process. Still looking for another explanation of that one, because I refuse to believe that the HPL engine doesn't understand visibility culling. RE: Penumbra Performance Problems? - Thaliur - 04-09-2007 I can't see any reason for the tech demo -> Overture performance decrease, but the Framerate differences in Overture seem to be caused by what you could see if it was bright enough. Maybe a texture pipeline issue, or something about the physics calculations (though these would also occur when you're not looking at them, so I guess it's not their fault). This is weird. Maybe it isn't a problem with your graphics, but with your sound chip. Some sound chip have a hard time handling directional audio or environmental effects (especially OnBoard-Chips). The old mine has a lot of natural sounds, at least I got that impression, and maybe when you turn towards that dead end, some of them have to be processed intensely. RE: Penumbra Performance Problems? - SirRaven - 04-09-2007 Scrap your video drivers. 93.71 is so freaking buggy it is pathetic. I have a 7600GT-CO and I had to revert back to 84.21 drivers cuz the 93.71 would lower my performance in some games and had problems moderating my gpu fan speed. I could almost guarantee your problem is driver related....I haven't seen such a bad batch come out of nvidia in a long time.

I was suspecting wonky drivers, but no one else had complained that the newest ones were giving them ass-poor results. I'll try this when I get home and report back ASAP.
