Dual Monitor Preformance

[MrSanderzX]

My system is currently running three monitors. I have noticed that my system doesn't seem to be running as well as it should considering my systems specs. I was wondering if anyone has had any problems with poor preformance because of multi-monitor setups.

My system is as follows:

Shuttle XPC - SB75G2
Intel 2.8 Prescott
OCZ 1Gig Dual Channel PC400
Western Digital 36GB Raptor
BFG 6800 OC 128
Voodoo3 PCI (Controls the third monitor)

I can only pull 3509 in 3DMark05 and most games are preforming like I am running off my old ATI 9500. I have cleaned out all the old drivers from my previous card, so I am pretty sure there isn't a ATI Nvida conflict present.

Any help would be nice. Thanks in advance.

bump for help.

because your card has to render over 3 monitors maybe?3509 is good for a 2.4ghz p4. what resolutions are you running?

nvidia has known performance issues when runnin multiple monitors and 3d apps, reference a couple of "Doom 3: Help Me!" threads right here on these forums. ATI does much better in these regards, IMHO.

Well, I noticed a major slowdown in terms of even 2D app performance, when I was running a triple-monitor rig with three PCI Matrox Millenium cards on a K6-2 400 rig, but that could have been due to any number of reasons most likely unrelated to yours: 1) underpowered CPU for running all of those apps, period, 2) only 4MB cards, so things like font/bitmap caching were not very effective, and had to be performed out of system memory over the shared PCI bus, and by the main CPU, for all three displays, 3) driver issues - "bus mastering" mode would seemingly switch off after a period of time in operation, seemingly randomly, on some of the cards. I have no idea why. It was clear which cards were running with that enabled vs disabled though, because you could click the title-bars of windows and drag them around, and the non-BM displays would be noticably slower. That could be due to some Windows' primary/secondary acceleration functionality too. (This was on W2K.)
PS. Which drivers are you using for the V3, to use it as a secondary display? The XP out-of-box ones, or some 3rd-party ones?
