I always thought that for DOS applications the VGA's memory size has no effect on performance.
Recently I upgraded an ISA Cirrus Logic 5424 from 512KB->1MB and decided for no reason at all (well, killing time during the lockdown is the reason...) to do a before-after comparison, on the same 386 PC of course.
I was expecting to see identical results, but no.
Consistently 3DBench had a score increase of 6% and Doom's fps increased by 8%
My question (and point of discussion) is what's causing this performance increase. Is it the software that's benefiting from the extra memory somehow? Or do such old cards implement some kind of interleaving and the card actually becomes faster?
I find hard to believe the latter. In any case and whatever the reason is, I just busted a myth of mine and I believe of many: performance does increase. I'm tempted to see if I have other upgradeable cards (or with socketed memory that I can remove) to see if this is a common behavior for all cards or only a few do something with the extra ram.
