A question about CrossfireX and Arma2 CO

Recommended Posts

Hello.

Ive been playing arma2 co for a little while now and i have some questions about the performance of CrossfireX in the game.

I run a

Athlon II x4 630 2.8

10 gig ddr3 system ram

dual 5770s

win7

1.5T hdd.

Dual 22in monitors

Latest Bios

Latest Catalyst driver

Latest App profiles

Latest Arma2 patch

On my second monitor i run MSI afterburner monitor to watch the GPU core speeds

And i run a CPU monitor to watch the cores % and temps of my CPU.

What ive noticed is that when i just load the basic loading screens for areas.

for example i use the E08 Benchmark for my tests.

when i exit that bench mark i get either the snipers or the Guys over looking a town Load screens.

when im on the load screens my GPUS run at 90-100% load and i get good fps results

when im in the benchmark or ingame the GPUS run at anything from 30%-80% and very very seldom reach 90+%

both ingame and in load screens my CPU never passes 70%

and varies from 30-70%

Could someone Explain why this is and if i can do anything to increase the GPU loads for ingame or benchmark play ?

Also multiplay games my GPU loads never pass 50% and are mostly in the 30% range (?????)

Thanks in advance

PS. My E08 benchmark is 50-55 fps depending on the settings i use ingame @ 1920-1080 x 1920-1080 aa off

PPs. here is a link to a screenshot of my desktops showing the arma2 benhmark and the GPU monitor results as you can see from the GPUS usage at the start its level at 90-100% on the load screen drops to 0% as the benchmark loads then never hits the same levels again during the whole benchmark even the most intensive section of the benchmark doesnt pass 80%. This is the same ingame.

well, you're very likely cpu limited. Try throwing a couple of smoke grenades and zooming in on the smoke, that should get your gpu use up.

you can also try to lighten the cpu load by running with less viewdistance, terrain and model detail. And make sure shadows are on high or very high.

Ok thanks ill try that.

should have a new cpu coming soon aswell so ill see if that makes a difrence to the gpu loads

Hello again.

I just installed a new Cpu.

thought maybe someone might like the info on the difference it made to my graphics cards during E08 benchmark.

I went from an Athlon x4 630 2.8mhz to a Phenom II x6 1090t Oced @ 4.0mhz.

still using 2 ati 5770s clock speeds 875 - 1250 on both cards.

the e08 benchmark results are 75-80fps an increase of 25 - 30 fps

but the main thing is my GPUs are working alot better ingame and during the Benchmark.

90+% all the time in bench mark.

see link for graph of GPUS during benchmark.

Im Happy :)

hope this helps someone somehow :)

Try 2 check benchmark 2 gpu usage, and see 90% :j:

Benchmark 2 is messed up it doesnt use the gpus hardly.

it stays at 0 usage on both gpus then jumps to 100% on gpu2 for 3 seconds then drops to 0% again

it does this every time

thats why i dont use benchmark 2 :)

Benchmark 2 is a monster! It really stresses your CPU. If your CPU can't handle it, it will bottleneck your GPU.
