Software mode dependent on RAMDAC rendering?

[CleanSlate]

I heard this today, I am unsure what to think but it makes sense in this example:

2.53 ghz p4 w/ an onboard intel POS gfx card

VS

my 2200+ << clocked 2600+ barton with a 4x agp gf 2 gts (see sig)

Game: www.wulfram.com


Results(software mode only):

2.53 gets a higher peak fps but in battles the fps drops to 30-40 from 85 or higher. The drop in fps causes major system laggage and my aim goes all to hell.

Yet with my 2200+ my fps peaks lower at about 80 fps but stays constant 60+ fps in full all out combat with no real laggage caused by the fps.


Are my findings accurate as the only thing I can think of is that my 350 mhz ramdac on my gf2 gts is owning the pos intel onboard gfx card's ramdac (if it even has one?).

Th RAMDAC does is reads the frame-buffer and converts it to an analog signalf for the monitor. Any video card (unless it's an all digital pure DVI one...) is going to have one. As for the speed, the only thing a faster RAMDAC allows for is higher resolutions & refresh rates; it has nothing to do with performance.

If anything, I'd think that the P4's taking a hit because the onboard gfx are using shared memory & there's contention for the bandwidth.

Good point
