Witcher 2 Crossfire Performance

[thilanliyan]

Xfire was working for me with 12.1 (I think) and W2.

 

[RavenSEAL]

I had scaling issues like your described but I fixed them by cleaning and reinstalling drivers. From your op, it looks like you already did that...

Is the performance the same with crossfire disabled?

It's better. No stuttering, same FPS.

 

[RavenSEAL]

This is frustrating, I'm about to pull the trigger on an HD 6970.

 

[RavenSEAL]

Gonna pull of another driver sweeper for the hell of it...

Also, did you actually uninstall the drivers via device manager? When I had these kinds of issues I would uninstall the most recent drivers, reboot and find windows had loaded an older version. Cleaning via device manager until the cards were using the bog standard windows driver. Then after reinstalling the newest drivers my issues went away.

It is frustrating, but I think it is something up with your system. Once I had my drivers all cleaned out my dual 6970s did very well with W2

Same drive team? 6970 can't be much faster than a single 6870 @ 950 core.

Why not try to trade for two 560's?

 

[RavenSEAL]

I think things are back up to speed with the driver sweep(I actually used driver sweeper this time around). Let's see how the game behaves itself for a while.

 

[RavenSEAL]

Well, the scaling has improved a bit to say the least. Still not where I like it..

 

[RavenSEAL]

Well, I'm not sure who I should be pist off at...AMD or RedP...

 

[thilanliyan]

How exactly is it performing now? You're probably not gonna see like 120fps constantly at 1080p with 6870s. Look at XFire reviews with W2...it is pretty taxing.

I'm seeing 30-50 fps at medium settings

scaling could just be busted on the 6870s. Are you using the stock "medium" settings or did you tweak things around with the engine options? LOD can really kill performance in that game.

I destroyed this title on 2 460's with the same setup, frames were solid so it shouldn't be the CPU. That game definitely benefits from additional gpu power though so maybe try applying one of the previous driver patch fix's if possible.

 

[PrincessFrosty]

It's worth keeping in mind that it's generally a very demanding game anyway, I'm at something like medium settings with a few tweaks to keep a consistently high FPS on my 580, however that's at 2560x1600.

Actually come to think of it, it's probably one of the most demanding games on the PC right now.

Yeah, the negative scaling is clearly there....

The game plays like crap on crossfire but smoother on a single card and the framerates are almost identical.

What is the gpu usage with crossfire enabled? Load up msi afterburner and chart your cards.

It goes from anywhere to 40% to 73%. With Crossfire disabled, the card is smashing the wall hardcore style at 99%/75C.

 

[Ferzerp]

What is your per core processor utilization at this time?

Haven't bothered checking it based on the GPU figures I'm getting. From what I read, the game supports up to 20 threads.

it's 25% faster that's pretty substantial but definitely not worth upgrading

Yeah. Anything short of a 7970 or a GTX 680 is a downgrade performance wise. Too bad I don't have that kind of money :\

So there is nothing anyone can add?

Since it was about time I reinstated my secondary system in proper working condition (and what better incentive than a Witcher 2 test), I checked the game again, latest Steam version, Catalyst 12.3 plus APP 12.3 Cap 1, 5850 crossfire stock, cpu is a Q9550@4Ghz.

As you can see, both cards show max gpu usage and the resulting framerate is pretty good.



Settings used where factored in as follows:

Ultra settings, minus vsync, minus ubersampling, minus everything blur related, minus everything depth of field related.

I also did a quick run through at this part of the game to see how the gpu usage would fluctuate. It didn't.



So from where I'm standing crossfire works great, as it did before, on my 5850s.

Is your crossfire kicking in properly for something that it would normally, like Unigine Heaven?

Battlefield 3 and Skyrim weren't giving me any issues last time I took them for a spin...

I'll try again tonight, maybe switch the card's PCIe slots.

 

[Ferzerp]

Worst case scenario, throw a spare HD in it and do a clean install, just update it, install all the drivers, and witcher 2. See how it acts then. If it's fine, you know you've a software issue. If it doesn't help, just stick the old drive back in.

 

[RavenSEAL]

Wow, something is tripping balls right now. My overclocking utilities aren't showing the GPU/memory clocks nor are allowing me to change them...
