Far cry 3 Strange sli usage ?

[Mr. May]

I have 3 670's set up in tri sli but with sli enabled im getting ....

0-10%
90-99%
0-10%

Which is only giving me about 40fps maxxed with 2x AA at 2560x1440

How can I get it to use all 3 cards ?

I am on the latest betas and it tells me both GPUs are being used 99% but in game, I am getting 20fps @ 5760*1080 Hopefully this is just temporary.

7970/50 CrossFireX-Max everything.

Anywhere between 45-90 fps depending where/time you are in the game, both gpu's@99%.

Such a good looking game Tommy but unplayable at those fps

Nvidia messed up the profile on the latest betas if running farcry3dx11.exe

the fix for sli usage is in the far cry 3 thread

 

[Mr. May]

The nvidia inspector DX11 compatability bit ?

Tried it and it does not work for me

 

[Twirlywoos]

yes that's the one, you had to change some kind of hex value too iirc.

maybe there's some info in this thread:

It certainly is greg, I can turn down the 8xMSAA, but I want the best I can get out a title, performance is ok I suppose and 45's playable enough for me, but hopefully AMD/Nvidia can wrestle some more performance from it.

The engine cut scenes are far from smooth though despite the frame counter not budging, my first case of microsstutter with CrossFire perhaps or it's an engine thing, hoping it's the latter though that can be sorted.

I have been playing it a fair bit and seen frames drop to around 14fps in places generally sits around 24fps and is not smooth at all. I think I need to leave it alone till some more performance is available or I have to turn settings down. I have a few games from the steam sale and the humblebumble deal to keep me occupied for a while... Still annoying, as it is a good game

 

[tommybhoy]

Yes, I'm a bit like that myself greg, I usually try out a game for release performance, then wait a bit for optimisation before I come back for a proper playthrough-here's looking at you Hitman as the biggest culprit of late.

The performance is ok'ish but should be better considering what's pushing it in my rig.

I only bought Dawnguard and resisted any more purchases this time round in the steam sales as I have loads of titles to be played first anyway.

FC3 is looking like a good game though.
