Low FPS with i7 2600k and 6950 CF

[drunknmunkey666]

With that CPU you could be encoding an long mp3 in the background without performance-loss, I think..
I got a Q6600@2,4GHz - and my game runs at 45-50 fps with a GTX560ti..

And in many games, all textures are loaded to RAM and switched back and forth between gfx-RAM and normal RAM - this is where PCI-speed steps in (but that's not an issue for anybody these days.. Studies shows that there's NO performance-loss at PCIe x8 or even at x4).. No serious game loads textures from disk in the middle of a game, that's done at the loading screen to RAM.

I maintain my idea about the fault is located in the crossfire-profile or something related to that...

Do you got any clue how to fix this if that's my problem?

Have You installed latest CAP's along with drivers? Seems that Your CF is not scaling at all. You can also try forcing CrossFire profile with RadeonPro (Dirt2 profile + Alternate Frame Rendering will be ok though it seems worse than profile from CAP). Bear in mind that that game can drop to 20 fps with Uber in certain places (lots of NPS's), at least for me it does and thats why i always had Ubersampling off. Running on 2 OCed 5870 and 6 core intel here.

i know that The Witcher 2 is very demanding but when my card ain't scaling more then 50% something is wrong.

I got a problem with The Witcher 2!
I only got 50% Gpu on booth gpu's and an average framerate of 15-20(1920X1080 Ultra, UberSampeling on)
The weird thing is that when i'm looking at the ground i get like 80-90% Gpu usage but when iäm looking up it drop down to 50% again.

I really need help with this one please!

My Specs
Intel Core i7 2600k, stock clock
MSI HD6950 CF 840MHZ 1350 MHZ
8GB ram Corsair XMS 1333mhz

Try turning off ubersampling. What fps do you have then?

Cross-posted. You have another thread on the same topic here: http://en.thewitcher.com/forum/index.php?/topic/24039-low-fps-with-i7-2600k-and-6950-cf

If you cross-post, you confuse the people who are trying to help you.

Sorry but the reason i posted a new one was because i have come up with the problem. As i stated in this thread. I thought the other one was a little bit confusing.

I got like minimum 40 and highest 60 on the first map without Uber.

if u have everything to the absolute max i think 17fps are normal for ur config
if i put all settings to max i get 50-60 fps so thats with ubersampling on
however if i put uber off i never drop below 100 fps so i think amd cards just arent great with ubersampling.

i have 3 6970s in crossfire all overclocked to 1ghz and a 980x @ 4.2ghz

so i would say just try auto detect best settings and go with it. or atleast leave ubersampling off if using amd cards.
