Cedega 5.1 and CS: Source performance

[eqisow]

I have recently downloaded and installed Cedega 5.1 and am attempting to play Counter-Strike: Source. Everything installs and launches fine, but I am getting absolutely horrible performance in game. At 640x480 with all settings on low I get something like 20-30 FPS. Somewhere between 6 months and a year ago I got Windows level performance (with slight graphical glitching) on the same system and Ubuntu Hoary, so I know better is possible. All of the system test in Cedega pass. The Cedega settings for Steam are currently at default, though I feel like I have tried every possible combination of settings. I have also tried Cedega versions 5.0.2, 5.0.3, and 5.1. System specs are as follows:

AMD 64 3000+
2GB DDR400 RAM
GeForce 6800 (128 MB) using 81.87 drivers
Kubuntu Breezy running 2.6.12-10 686 kernel.
Xorg version 6.8.2

Does anybody have any ideas on improving performance to something playable? Looking forward to hearing your input, thanks in advance.

I have just noticed that under Advanced Video Options in CS: Source it shows the hardware DX level as 7. This (I think) means that it is emulating DX9 features on the software level, which is not good. I tried adding '-dxlevel 90' to the launch options for CS:S. After doing this the hardware DX level shows up as 9.0 under the options... until I actually enter a game, in which case the hardware DX level shows up as 7 again and the extreme laginess ensues. Does anybody think that this is, in fact, the problem? If it is, what could I do aout it?

Well tbh, you shouldnt expect better performance under linux atm. Since Cedega emulates windows DX engine.

Furthermore, the contradiction here is that you are actually supposed to get better FPS and overall performance by using dxlevel 70 than 90. Since 90 is only supported "fully" by the newest cards, and I doubt there is much support or value for those when running steam under linux.

[eqisow]

It's a reproduction of the Windows/DX API, not an emulator... performance is usually near windows level on supported games with Cedega, I've even seen cases where it was better.

As far as the DX level my card is a DX9 card. Also, what CS is showing is hardware DX level 7, but software DX level 9; which is what is leading me to believe that it is emulating DX9 features on a software level. May be wrong on the assumption, however...

Also, others have reported much better performance than what I'm getting and I've even seen it myself. I don't think it's unreasonable to expect a little more.

Reading the forums today, I'm seeing other threads showing up talking about Cedega 5.1 blowing up 3D support. Your situation might be related.

[Peturrr]

Your problem seems to be Xorg / driver related.

You have several options under the 'screen' section, that should be under the 'device' section. These are:
Option "NoLogo" "on"
Option "RenderAccel" "true"
Option "BackingStore" "On"
Option "NvAgp" "1"

Maybe this will fix the problem.

I assume you have already read the HOWTO: latest nvidia drivers

[eqisow]

Lmao, so it would seem.... oops. Well unfortunately my entire X server is currently fubar'd, but I will try fixing that and see how it goes once things are running smoothly again.

Thanks Peturrr

(And yes, I did... in fact if you go to the end of the thread you'll see me witht he broken X server. )
