GPU usage only 35% in Diablo 3

[syntax_error]

current system:

Intel Core 2 Duo e8400 3.0ghz
XFX Radeon 6770
2gb DDR2 1066
WinXP

Hello.

Playing Skyrim the GPU is running at a constant 100% as reported by MSI afterburner. Runs fine at 1920x1200.

Playing Diablo 3 I've noticed that the GPU usage doesn't ever go over 35%. FPS will run an average of 50fps, but will drop below 30 when there is alot of action on the screen.

Is the video card being bottlenecked by the CPU during D3?

In the process of getting together an Ivy Bridge system, but that won't be for another two months.

Blizzard still dont know to code Wow after have run it during nearly 7 years.. so the beta of Diablo ...


its a beta...


Your gpuz usage suggest your cpu is is not enough, but seriously i will not think that with a 6770 .

I agree that it's the game as cpu seems to matter very little

your very meager 2gb of ram could def be a major contributor

I'll try borrowing some more ram from another system, but under winXP I'll top off at 3gb. Surely the 1gb of Vram on the video card should count for something?

VRAM won't do anything to help if the problem is not enough system ram - it is there to store mainly the texture files and the frame buffer, as well as in progress frames.

If you system is running out of system ram and having to hit the pagefile on the HDD that will slow down any system.

A co-worker suggested that I may need to open up a port to allow D3 to run at full speed and utilize more of the GPU.

This was the case with some WoW players.

Does this sound plausible for D3? Other than D3 and a little bit of Skyrim I haven't done any gaming since Diablo 2.

Later today I'll try bumping my system ram up to 3gb.

See if you can find a program to display CPU usage (and RAM while you're at it) in game along with the GPU usage.

You can try setting up port forwarding on your router and system firewall. It's usually a good idea for online games, see what ports blizzard recommends to forward.

Also, what in game settings are you using?

[shadow_craft]

Im sorry, but your system will experience some slow down.

The video card may not be stressed (and settings are probably set to low), but the other components of your system are the bottleneck. (cpu and memory bandwidth mostly)

Disable frame limiter and v-sync in game and see how it work out for you.

Checking MSI Afterburner I realized that the 35% showing was my Fan Speed % and not GPU %. I was probably messing with it a while back and didn't save the proper settings I wanted. Silly me.

The GPU does indeed run at 100%. CPU according to Task Manager hovers around 50%ish on both cores. Around 700mb of Physical Memory remaining.

Seems to be better after configuring ports. Figure now that the dips below 30 were Battlenet server issues. Now remembering how D2 would lag horrendously at random times.

Running 1920x1200 resolution, High/Medium quality settings, VSync disabled, No AA. Getting around 60-70 fps, dipping maybe to 45.

What ports did you need to configure?

I have some ping issues sometime, others its brilliant.
