EDIT: SOLVED. If you have performance issues with AMD Crossfire setups, make sure your game is patched to 1.2, solved everything for me.

I'm running The Witcher 2 with HD6950 CrossfireX, 2500K and 4GB of DDR3.

If I lower the settings to medium and the resolution to 1920x1080p, I manage to get 30-40 FPS. If I put in the settings I think I should be able to run (med/high at 2560x1440), my FPS is something like 20.

I'm using latest Catalyst drivers (11.6) and CAP2.

My GPU usage seems to be around 30% for both GPU's.

Is there any way to fix the performance? Obviously this can't be the actual performance I should be getting.

Oh and by the way, the game won't start in fullscreen, unless I change my desktop resolution to lower than native (2560x1440). After that I can start the game itself even in native resolution. I have no idea what could be causing this.

The only thing I can recommend is turning off ultrasampling, but I have a feeling you have already tried that.

Delete your 3D vision drivers. They can cause problems.

Check if Ubersampling is OFF!.

Else; make sure you are using the latest drivers for AMD.

Catalyst 11.6 - http://sites.amd.com/us/game/downloads/Pages/downloads.aspx

And then install

Catalyst 11.6 Cap 2 - http://sites.amd.com/us/game/downloads/Pages/crossfirex-app-profiles.aspx

---

Else if the above doesn't work, you can probably check out 11.7 Developer build.. -
http://developer.amd.com/tools/gDEBugger/Pages/default.aspx

*WARNING probably BETA DRIVERS/EARLY NON-WHQL builds*..so 11.7 is at your satisfaction and risk.

And then install Catalyst 11.6 Cap 2 over 11.7 developer build.

I'm going to bet you have Ubersampling on.

Ubersampling is off, I have tried Catalyst 11.5 and 11.6 with latest CAP. I'll probably try 11.7 dev build later today.

I don't believe I have 3D vision drivers, since I got AMD GPU, not Nvidia.

I disabled CrossfireX (so I'm running with only one GPU) and actually got a little higher FPS. I had some huge FPS drops at start, but when I continued the game ran pretty smoothly, except for some random freezes when entering cutscenes. I didn't try increasing the resolution or details, but I doubt a single GPU could run the game very well at 2560x1440.

Has anyone managed to get this game to run properly with a CrossfireX-setup?

I can run most of the recent AAA-titles @ 2560x1440 with high settings and some MSAA, while maintaining 60 FPS. Usually dropping the MSAA is enough if I encounter problems.

The Witcher 2 sure looks awesome, but it can't be this heavy. I don't expect to run it maxed, but this performance just sucks :/

I actually sold one of my 6970s because of this game. CF was slower than single card and I realized dual GPU support was going to be too dodgy for me to accept the geometric in crease in noise, heat, and power consumption.

But that was back before even the Witcher CAP came out. I'm surprised performance is still this bad.

On a single 6970 I'm getting 35-45 fps on 1080p. It looks like in your case, the CF performance hasn't improved at all.

Witcher 2 Crossfire performance issue was fixed way back in AMD Catalyst 11.5b drivers..so..

if not done so...
1. Do a full uninstallation of AMD drivers from your system.
2. Restart the PC
3. Install the new drivers (make sure to read the installation log after the end of the setup, to make sure there is a PASS/INSTALLED text for ATI drivers)
4. Restart the PC
5. Open up Catalyst Control and close it
6. Install latest CAPs from the link posted a few posts back.
7. Restart the PC
8. This..might sound crazy, if you are using Windows 7 or Vista..do a Windows System Assessment_Windows Experience Index from the My Computer->Properties screen (or it is at control Panel items->Performance Information and tools)..
9. After it is done, Launch Witcher 2 (make sure its updated, by default the launcher would have connected to Witcher 2 dev site and downloaded 1.2 version)
10. Open Witcher 2 options (from the launcher) and set the settings (Make sure Ubersampling is OFF, toggle it to ON and OFF just to be sure)
11. Save and run Witcher 2

If it still doesn't work faster than before, check how the game runs in Window Mode once...

If that didn't help, you can try disabling in-game Vsync and force Vsync+TripleBuffering using external Application (like D3Doverrider; but if you do this, make sure to set mousesmooth to 0 in the witcher 2's user.ini in mydocuments->witcher 2->config location).

I do not have crossfire, so I do not know if Vsync+TripleBuffering will work properly in Crossfire..but its worth to check it.

Try downloading the hotfix for TW2 from AMD site. Also win 7 has problem with CCC (it's known problem related to .net framework and token keys). If your CCC is not working the only solution is fresh install of the OS.

Did a fresh install of Witcher 2 and patched it to 1.2, fixed everything.

Now I'm getting steady 60FPS on high settings at 2560x1440. I can launch directly to fullscreen regardless of desktop resolution. Tthe gameplay doesn't feel weird anymore (had some sort of stuttering before, mouse felt strange etc.)

So, anyone having the same problem with Crossfire performance: 1.6 Catalyst drivers with CAP2 works just fine as long as your game is fully patched.

I'm pretty ashamed, should have tried this in the first place, but I didn't think I'd get like 400% performance boost from game patches ;)

Thanks for the help.

still don't think it was reinstalling the game + patch that fixed the game.

Did you restart computer after installing latest catalyst + CAPs? even if the computer doesn't say to do so it has to be done at least for the CAPs.

anyway, what matters is that you got it working :-)
