hey guys! I have a problem that i've never seen before and was wondering if any of you experienced this yet? when I try to run 3dmark05, it jumps out right after I start the benchmark and gives me an error:
"IDirect3DDevice9:Present failed:Device lost(D3DERR_DEVICELOST)"
I tried reinstalling 3dmark, nvidia drivers, and even directX - to no avail.
I'm pretty much clueless what could be the problem. also when I start quake4, it runs prettyslow, not like before. anybody?

funny I did a google search and found an answer in our very own forums. LOL

Looks like F@H can cause that... you folding when benchmarking? Looks like you are going to be shutting down or lowering the F@H CPU usage amount when gaming!
If it is F@H are you using the console or graphical client?

Yup. I received (I think) the same error and it was caused by F@H.

oh thank s a lot guys. I'm using the graphical client but the funny thing is that I have hyper threading and when folding my cpu is only @ 50% and few days into folding I had no problems with games at all (I guess they were using my cpu's other half). since I installed the quake 4 patch, quake4 is much slower instead of faster. heck I would be happy if it just didn't slow down because it was just fine before
I guess i will have to reinstall quake4 without the patch
but now at least iZ know whats wrong. thanks a lot.

When you see only 50% cpu used, It's because XP thinks there are 2 real cores.....your actually using ~98% cpu......
Are you folding while playing Quake? Because if you are, then the game will suffer big time......

he'd only be using 50% CPU because F@H and Windows only uses one thread for folding. Right?

kinda, folding sees 1 logical cpu....
folding will use all cache it can get, there is still only 1 FPU/ALU etc. so that gets used the same as a cpu without HT

With a SMT (Simultaneous Multi-Thread) enabled OS like Win2000/XP, Linux, etc. the operation system will identify the P4 3.06 GHz CPU as two logical processors that share the single physical CPU's resources. A physical processor can be thought of as the chip itself, whereas a logica processor is what the computer sees - with Hyper-Threading enabled the computer can have one physical processor installed in the motherboard, but the computer will see two logical processors, and treat the system as if there were actually two processors.
Here's a easy guide to hyperthreading
