If we look at the file the 190.38 drivers use for SLi profiles: C:\ProgramData\NVIDIA\NvApps.xml
(This is on Windows Vista and the "ProgramData" is a hidden system folder by default.)
We find an entry:
<PROFILE Label="Champions Online">
<PROPERTY Label="multichip_rendering_mode" Value="0x02402005" Default="0x02402005" Itemtype="predefined"/>
<APPLICATION Label="champions online/tip/gameclient.exe"/>
</PROFILE>
The profile never activates because it is looking for something that doesn't exist.
Use notepad to edit the file:
change: <APLICATION Label="champions online/tip/gameclient.exe"/>
to: <APLICATION Label="gameclient.exe"/>
I did not have to reboot to have this change take effect. Don't have Champions Online running when you do this.
Notes:
- When you update your video driver this change will get removed. You'll have to do it again if nVidia hasn't corrected the profile.
- If you have added a custom SLi profile for something else that also uses the program name "gameclient.exe" the drivers will get confused.
- "Champions Online.exe" is the game launcher and not the program that needs to trigger SLi mode.
- This post assumes a intermediate level of Windows knowledge like how to get to see hidden system folders or how to edit a file ending in ".xml" with notepad. There are many ways to get the same results. Search the web if you want to learn. It is easy stuff once you know how. I don't want to add things like that to this post.
A final mention about what this should do, increase frame rates. It didn't do much for me at first. About 24fps without SLi to 30fps with SLi. After tweaking with settings both at the nVidia driver level and the games video options it was by completely disabling the game's anti-aliasing that let my system go from about 30 to 60fps (I have V-Sync enable). I tried setting the driver to override the game and enhance it but neither helped.
The game seems to use its own anti-aliasing code and ignores the driver's. The games anti-aliasing code is not very efficient. Even at x8 it doesn't do a very good job. I play at 1920x1080. You can tell it is doing something at x2, x4, and x8 but the 'jaggyness' is still significant. FPS is also the same regardless of the amount of anti-aliasing (x2, x4, x8) further indicating it isn't working well.
I did not disbale my UI for this testing. That is a good troubleshooting / fact finding thing to do to help them track down performance issues in the code but it is not a playble solution.
Intel i7 920 OC'd to 3.8GHz
x2 8800 GT in SLi (Zotac's 1GB G92 cards)
3D Mark Vantage using the high presets I get GPU 7074 and CPU 17639 if you want a rough way to gage the performance you may get.
