Windows 7: TDU 2 performance is below par

So as the days go by Crossfire is beginning to annoy me more and more; I have the latest CAP Profiles installed and with 2 instances of GPU-Z open, the second card isn't be loaded much if at all. I'm seeing frames in the 40's and it's not making any sense to me at all. I should make mention that the frames will jump up into the 70's momentarily before going right back down to the 40's range.



Like I said, annoying. Anyone have any idea what's going on?

Heya Terronium 12

I've the game myself on my lower end laptop with an AMD GPU.... and yes.. the game runs notoriously bad on AMD hardware compared to NVIDIA's GPUs... even more so with CFX....

It's just bad optimization for AMD GPUs all around with poor utilization.. (try running the game in windowed mode with GPUz in the background to check for GPU utilization and you'll see what i mean).. The game doesn't even max out the GPUs...

Iirc, TDU2 was another non CF friendly game where the 'fix' was to disable to the 2nd card.

The fact that GPU-Z is reporting virtually zero usage suggests that the 'disable fix' is still in effect.


Tbh, you're going to find quite a few games where CF makes flap all difference.

(Personally, years of CF and CAT drivers are what sent me back to single GPU and nvidia for a year. I actually took a year off from multiple GPU's because 'the quirks' shit me so much.

So far my SLI 670's aren't as problematic, but that single year with one GPU was the least frustrating year of gameplay I've ever had )

Yep. Card 1 - 99%
Card 2 - Naught


That's really annoying, you know? Starting to make me wish I hadn't spent that $200 and put it toward a 670 or 680.

Oh yeah, I know it's annoying

You'll appreciate it on games that it works though.

(and if you end up selling both and going to nvidia - forget the 680. The 670 is a much better prospect. This is coming from someone who normally buys the top tier cards )

I do and that's probably what makes it that much worse. It has it's benefits in more games that I have than it doesn't, but I'd like it across all of 'em.

Blur benefits from it quite well although I'm not entirely sure if it's DX10 or 11, but the frames are in the mid to high 80's.
