Noticed it in the last few weeks though have reinstalled Vista twice(once to 64 bit to test it)
My Pc specs are Q6600
VHP 64 bit
4 gigs ddr2 ocz ram
8800GT 256mb DDR3
The problem is that I am getting FPS spikes.
Sometimes the FPS is fine for ps1 emulators then Id get lag spikes and framerate drops that stick, even if emulator is closed and not used, other times I can get perfect fps with no slowdown.
So I just assumed it was the emulator or I didnt have a good enough pc
But what got me going was I reset the emulator values down to minimum and shrunk resolution to lowest(lower than 800 by 600) and still the pc went one frame and lagged even on 2d games.
Then I played World Of Warcraft and it was fine for a few minutes at 60fps(at 1650x1050 resolution I think) then dropped to 50 then 40 then 30)
But there was nothing there on screen, no enemys no spells, no lighting.
I turned around and ran back the way I came and fps went back up within a minute
But a minute later it spiked down again walking where I was a few minutes before with no lag.
Is my graphics card knackered?
