Lost Planet CPU Usage unacceptable

post #1 of 15
Thread Starter 
Alright so I fire up the first DX10 demo right..

15% CPU usage across the board, it doesnt even fully use 1 core, it uses like 6% of each core, thats it. Nice coding.

This seems very unacceptable for a DX10 game.

Just wondering what your guys FPS, and CPU usage was for this. I have to set shadows to medium to get playable frames, everything is maxed and set on high other then that, 4x aa, 16x af, and 1920x1200.

I understand that SLI doesnt work with DX10 yet, but a QX6700 and 1 8800GTX should max this game without much problem, It seems to me that since the game only uses 15% cpu i'm getting a huge bottleneck.

I thought that DX10 took a lot of workload off the CPU and put it on the GPU, which is probably why you're bottlenecking, if SLi doesn't work properly with DX10..

Just found out the new beta drivers support SLI in this game, so I'm gonna give that a shot.

your using windows right? the reason you get usage spread among all the cores is windows not your game.

DX10 and multi-threaded code are completely unrelated.

That the DX 10 is putting more work on the GPU, is that good? Seriously i dont anderstand why cpu and gpu cant cooperate,. Why has it to be that the GPU usage is 100% and the CPU usage is 15%. I dont se why is better?

How are you running 1900x1200 the demo doesn't even support my 1440x900?

Well, the important question is, does the demo run well?

If it doesn't hog CPU cycles, that's not inherently a bad thing. In fact, if it runs well and doesn't overly tax the CPU, that's a *good* thing.

Well I downloaded the beta driver that allows DX10 sli, and my frames are worse with SLI enabled, on all 3 rendering modes. Unplayable at anywhere near max now. Even with motion blur off I still don't get decent 20+ FPS frames.

Mhil my demo allows me to set it to 1920x1200.

This game has to be coded badly, or just needing a driver release for it.

DX10 is not putting more work on the GPU, per say. It puts less work on the CPU than the DX9. The CPU controls the GPU and has to send it instructions. For example, DX9 required the CPU to to send it 10 instructions to draw the same thing 10 times. DX10 would require the CPU to send 1 instruction which includes the command to draw the same thing 10 times. Hence, the CPU does not have to waste as much time directing the GPU.
