AMD - How To Overclock The Official Way Using Afterburner + Step By Step Overclocking Guide + Comple

Overclocked -

It did go up to 90% GPU Usage but not very often, It appeared to be the higher end of 70% though but also in the 60's. Again, it went in to 90% at the end of the benchmark.

Stock -

Mainly in the 80-90% region. Very often in the 90's.

CPU bottleneck?

Some input from other ocuk'ers would be great. I can't figure out why you aren't maxing gpu usage.

What drivers are you using?

Catalyst 13.1.

So I should be 99% GPU Usage all the time?

You should be with vsync off unless you have a cpu bottleneck. Sleeping dogs is a gpu limited game.

In unigine it is constantly 99%. Is that an irrelevant comparison though?

Cheers

Not really as Unigine is about as demanding on the cpu as windows task manager.

Hopefully someone else can offer their 2cents.

If you keep the settings the same but put the res down to 1680x1050 how does that affect gpu usage?

GPU Usage appears to go even lower with a lower res.

Running AA on Extreme maxes out at 90-99% though. Obviously performance is lower - Could that still indicate a bottleneck?

I'm not 100% sure Tom. I'm hoping someone with more knowledge will contribute something. However i think you might have a slight bottleneck. Try running Extreme, vsync off, SSAA high with gpu overclocked, try your cpu at stock then overclocked as far as you can push it. If you see higher gpu usage when cpu is overclocked then i guess you have a bottleneck. As far as i understand it anyway.

I don't even have this CPU OC'd though as for only 200MHz I really don't want the hassle of it all. i3 3220 literally won't clock higher than 200Mhz.

Not sure what to do now... Just want everything to be running ok. :/

Well it might be worth trying to squeeze what you can from it.

As long as the game runs ok though does it matter? All it means is that your cpu is holding the gpu back a little.

Yeah I guess so. It's just weird because I'm playing as normal now in a more dense area and my GPU is at 90%. Maybe it's just normal...

In theory i can't see it providing a bottleneck (ivybridge i3 with hyper threading) but the lack of 99% gpu usage with vsync off is strange.

Hmm... Weird. Let me know when you get the chance to test.

Drake5 · 17 Mar 2013 at 22:07

SSAO was on Normal instead of High. With it on High, GPU usage pretty much always locks out at 99% with VSYNC off in benchmark.

I have enough grey hairs without you giving me more Tom.

Normal service is resumed.

Drake5 · 17 Mar 2013 at 22:31

I was a bit iffy at first but I posted up the screenshots with it being on Normal, you didn't mention it so I thought that's how it was intended. Haha, I'm such a fool!

Drake5 · 17 Mar 2013 at 23:21

Just another little observation from actually playing. Whilst GPU usage is now a lot higher it's still not a constant 99% but it's not far between. It can go to the deep 80's sometimes and then varies up to 99%.

Well maybe a slight bottle neck is apparent. It should be hitting 99% constant with vsync off tbh. But its not as bad as originally thought.

So basically I need a better CPU?

It might be holding the gpu back slightly, that's all. Maybe better asking in the cpu section about this.
