LOW GPU usage r9 270x

[vladan]

yo, i have one problem i just bought r9 270x and in game i have gpu usage of max 50% (most of them from 20%-40%), on stress test its go to 100% but just there.

In GTA V if MSAA is of GPU usage is around 25-35% if i put 4x MSAA it go up to 45% MAX

 

Intel i3 2120 3.30ghz

Asus p8h61-m lx3

Sapphire r9 270x 2GB

2X2GB RAM Kingston hyperX 1600mhz

PSU is Corsair VS650

 

Win7 64bit

 

Really need to figure out problem and fix it.

Maybe is just bad reading, is the performance ok?

Is cpu capping out?

As above, what are you CPU readings like? If you're CPU is running around 100% then you have a CPU bottleneck, otherwise your GPU readings are glitching out. I have the same GPU and its 100% in most games except Dishonored where vsync limits it to 60fps.

either just a visual error or the CPU is bottlenecking

performance is not good, CPU 70-85% with old GPU AMD HD7750 i had similar performance

Ah hold up, 4GB RAM is not enough for GTA V. My PC was 4GB until my actual RAM came, and it uses it all up plus more. You won't get 100% GPU usage because the GPU has to wait while your system reads from the VRAM, which is super slow. More RAM will help.

Quick question in GTA V (just 'cause I have the same game and GPU), does performance drop hard once you start driving quickly? Or is it always bad?

yea it drop but like 5 max 10 fps, for me from 50 to 40, i didnt tested alot because i just get GPU

What settings do you run at? I'm running mostly high, with a couple on normal and 2xMSAA and I sit around 45-50fps generally at 100% usage

Normal, 2xMSAA FPS go from 60 to 40. when drive fast 30, But yea like i said i didnt had much time to test it full, i only notice that GPU usage is around 30% then i tried on MSAA x2 and GPU usage was max 45%.

Weird... I'd say definitely more RAM, then when you get time check out in game CPU usage to check for a bottleneck. If CPU usage is low as well, and RAM doesn't fix it, then I guess you have an error with your GPU usage. Try some different software for measuring usage as well.

CPU usage is from 75% max 90%. Thanks for trying to help me, i will go with upgrade RAM for now and we will see happens.
