The game IS heavily dependent on GPU.

This game barely tasks my 2500k @ 4.8GHZ.

(Top four numbers are my CPU usage percentages while the bottom number is my GPU usage percentage.)

2500k
5850
^specs.

I do notice cores 1 and 2 do a lot less work than 3 and 4 however.

Everyone ITT: CPU Bottleneck trolololol.



Also what the heck! Turn on ambient occlusion, it's what makes the games shadows soft... That's like the best feature.


What program you using to track the usage of the CPU? can it also track the temp? thx in advance.

the program is called playclaw http://www.playclaw.com/ and yes it will track usage, temps and more

now about the AO, I could care less how pretty that shadow is on that leaf as I'm getting shot in the head.. or wow check out the bumps on the cobblestone...

I want nice graphics but not at a price that it going to take away from me seeing you before you see me..

:D

Q9550 overclocked to 3.8GHz
GTX 470 overclocked
8GB RAM

And my GPU usage is very low, usually around 30-55%, max I ever get is 65%. But it's never consistent and usually about 50%. I'm getting between 30-62fps, average i'd say in the high 30s low 40s.

Bumping because I have the same issue and a similar setup.

Stock GTX 470
Q6600 at stock 2.4GHz
8GB RAM
Used Nvidia system monitor to log GPU and CPU performance during a half-hour game on Apartments. GPU usage hovers between 40-60%, CPU usage across all 4 cores is about the same percentage with occasional 5 seconds of 100% on all cores.

Getting this aswell, i run an X4 @ 3.875ghz and a GTX480 @ 850/1700/4000.

Most of the time i get around 60/70%ish GPU usage and around 50/60fps BUT in certain areas (the big open area on the snow map for example) my framerate will drop to around 20fps and the GPU usage goes to 20/25%

This is annoying, having poor performance and the game not even using all processing power available.

I have a core i5, ram 4Gb and a nice 5850 (OC).

Runs everything at ULTRA except shadows, but I only get 60% GPU usage.
Menu is indeed a strange 100% of GPU.

I have a feeling that the GPU utilization issues have more to do with vendor drivers than they do with the game. Some GPUs fare fine, others don't go over 50% utilization. Mine (GTX 580) hovers close to the 70% mark. I hope that Nvidia AND ATI will optimize their drivers for RO2 soon.

Mine hovers between the 70-80% mark on my 9800GTX+, but drops occasionally for a second or 2 for no reason at all (temps are sub 70 under load). That does remove 10-15 FPS when that happens.

By any chance has anyone here tried leaving one frame thread lag enabled? For other UE3 games I've played it has improved GPU usage "slightly" it might be worth a try.

I have done this, and at least for me has given a modest increase to GPU usage. Certainly isn't a 'fix' but it could be a temporary workaround.

Hmmm .. this GPU under usage together with the CPU under usage smells at BUS bottleneck.

It is possible that the CPU is pushing too much data to the videocard bottlenecking the PCIE bus or the graphic card's own internal BUS. Seems strange but it could be one cause.

Another cause what I see on my dual core CPU, there is a lot of CPU system time usage which can be associated with the the PCIE bus usage (a lot of interrupts) or massive context switching.

Is this the original UE engine version or is a re-compiled version by TWI?

Another tweak I thought you'd all like to know, open the launch options for the game in Steam, and add the line -compatscale=4. This will keep your CPU and GPU more in line with each other.

To see if this will make a difference for you, run the game and use the 'stat unit' console command, this will show you if your GPU and CPU are working at the same level. The Frame, Draw, and GPU values should be roughly the same; if they aren't forcing compatscale=4 should be a temporary fix.

thanks i'll try this

With out without SLI enable, I have this low GPU usage, it goes from 54% to 90% with an average 65%...

We really need a fix :'(

I made these graphs with ATI Tray Tool. As you can see the GPU activity/usage (green) is very low in RO2 (And Brink, but this game is a differen story ...)
I made one while playing BC2 (and JC2) where the usage of the GPU is normal. So my graphics card shouldn't be the problem.

My PC: ATI Radeon HD 5850, AMD Phenom II X4 955, 4GB Ram, Gigabyte GA-880GA-UD3H

I tried it, but it hasn't changed anything.

Compatscale=4 does nothing to me, even if i noticed a little less "lag"

But my framerate is low and my 2 GPUs usage is very low, check this out
