I'm unsure whether this is actually GPU related or not and so far I've not notived this affect any other techdemo/game/application but..
I have recently built my new box, as in autosignature, with XP x64, and I have to say I'm genuinely impressed however I have noticed when running "rthdribl" it skips every 3/4 seconds.
I routinely get around the 150+ fps mark (running with it's defaults) but every 3/4 seconds it takes a serious dive, a split second 50/60fps drop and then back upto the 150+ mark.
I'm running the card at stock, I'm using the pmtimer flag, thinking it was perhaps skipping between one core and the other (on my dual 4800) but well, I'm stumped. Oh and i'm using the offical 84.25 drivers.
Anyone else notice a similar effect?
Cheers, Paul.
EDIT - I have now also tried 3dc and I do believe it is doing exactly the same thing also, around the 900 mark and drops 300/400 for a split second every 3 or so seconds. Hmmmm.
EDIT - Oh ok, I'll explain it away myself shortly. Issue only occurs when running in windowed mode, i.e. if it's full screened, no skipping. odd...
EDIT - typo's
