Hey Guys,

Started playing Sleeping Dogs last night and am getting shocking FPS, about 25 - 30fps max dipping down to single digits at points! This is at 1440p but with R9 290 crossfire?! I even tried the low preset in graphics settings and problem persists. I've even tried 1080p but no improvement.

Also I'm noticing only 1 CPU core (3570k) is being utilised according to Afterburner. Core 1 is at 100%, while 2, 3 and 4 max about 5% usage. See screen shot below.

I've ran just one card to see if my CPU is bottlenecking, (it's currently at stock as my H100 died last week, once RMA is complete it will be back up to 4.5ghz), anyway problem persists with one card.

I'm using a clean install of 14.3, problem persists but no probs with the drivers so far! It's the same with 13.12.

In games settings are set to Extreme but AA is stepped back to high.

I think the problem is Sleeping Dogs is only using 1 CPU core so only 25% of my processing power. You can see both GPUs usage up and down all over the place and only CPU core 1 maxed out, the rest hardly even registering!

Any ideas?!

And I have two of them! vsync doesn't make a difference unfortunately.

It has to be something to do with the CPU usage. The grunt is there in the cards but with the game only using one core, (25% of my CPU power), the CPU is seriously bottlenecking the cards!

When you launch Sleeping Dogs, Alt+Tab back into Windows and open Task Manager. Click the Processes tab and look for the Sleeping Dogs .exe. Right-click it and click Set Affinity. You can specify how many processor cores should be used and you may find that only CPU 0 is selected.

This sounds like the kind of answer I'm looking for! Unfortunately I'm in work now so will try later when I get home and update, fingers crossed it works!

My bad but still i dont think so that a i5 3570k can bottleneck two r9 290 is the cpu overclocked?
