Not sure either, only suggestion would be to restart from the beginning: uninstall drivers, run Driver Sweeper, restart, install latest beta driver w/clean install checked, restart, install Nvidia Inspector (latest) and make sure you modify the profile SLI bits exactly.

There could be one other discrepancy - your version of Witcher 2. I have the GOG edition (DRM free), but there's also the retail edition, Steam edition, and Direct2Drive edition. I can confirm it works for GOG. On other editions, maybe in the Nvidia Control Panel under Custom Profiles add the game's executable manually? (witcher2.exe) Then go into Nvidia Inspector and do its changes.

Thanks for the reply. I have the retail version and have tried 3 sets of drivers. I'm back with betas again with 3d vision installed as it makes no difference to my set up which I find strange. I have even used the nvidia tool for importing and exporting profile to modify them which bypasses inspector completely.
So perhaps the fact that I have retail version with drm may be doing it, no way to find out really.

Mine worked on the steam edition. Just copy pasted the hex code and made sure that (The Witcher 2) wasn't in the same line as the hex code. I think it might be thinking that the title text is part of the profile code.

Works with GTX 570 SLI GOG edition.

Works for me- bumps up the GPU usage and FPS. But I get artifacts during gameplay. They only last a few milliseconds but they're frequent enough to ruin immersion. They stretch from the corner of the screen to the middle, and they're narrow-triangular.

The original Witcher had an issue with SLI enabled. You would see a blur/haze around torches and sources of light and they would also be visible through walls. As far as I know that issue was never fixed...and has carried over to Witcher 2 !! I hope a patch fixes this.

By default I don't have this issue. I only get light leakage when I use the hex code from the OP.

Awesome guide biggrin.gif. Got it working with my 580s with the SLI hack on my CHIV using the 270.61 driver.
