I have a problem. I run Windows XP and when I play games and a lot of particle affects go off my fps drops to around 5fps and it stays there and I have to quit the game and restart the game. But this seems to happen a lot. Ive tried....
A) I OC my video card and Ive tried it on the stock timings.. same either way.
B) New graphic drivers... no luck, tried 3 different drivers.
C) Tried lower graphics settings on the video game, no luck still happens.
This is my computer newly built a few weeks ago. At first this did not happen, it did not start till recently about a week ago. I only play 1 video game(Age of Conan) so I am not sure if this happens with other games.
I mean particles like a lot of people cast spells all at once..... I get no graphic distortion or anything I just get a decrease in FPS to around 5 and then it stays there.
I read in another thread about someone play WoW and it was their sutom UI.. so I attempting now to go back to the standard UI and see if it still happens. I dont see how it could be the UI but ill give it a try.
My setup is similar to yours except i run Vista, I noticed a particle slowdown today playing Project Torque(Settings maxed)
It dipped low enough for me to notice but it never got to 5fps . I took particles from High to the next setting down and it stopped doing it.
I use the exact same MSI card, oced to 780mhz. Haven't had any particle related problems. It's normal for fps to drop when there's a lot of particles on screen, but it shouldn't be nearly as low as 5fps.
Get RivaTuner and use the tool that graphs yer clock speeds and fan settings and all that. See if for some reason it is cutting your speeds in half. This just happened to me, but in an SLI setup.
What you need to do is attempt to do the overclock and when the screen comes up asking to reboot or...whatever else it is...do the reboot and it should hopefully reset the stock settings, then you can overclock again from there.
Still don't know what caused this. My only guess is a drop in power due to me adding a power sucking fan to my case. Then for some reason it could only power it up that far. I removed the fan and then noticed the lower clock speeds.
