TT VME Graphics - Revisited
Copied from my blog:TT VME Graphics - Revisited
Just recently I posted the article TT VME Bus Fix - Does it really make it faster? where I compared performance before and after Atari's VME Bus Fix which all REV.H motherboards and up seem to have. As kind of expected, the gains were not significant. I mean we would have noticed this years ago. What is unexpected, however, is the sudden performance boost (on average) than just a few days ago. So what has changed? Am I missing something? If so, let me know.
Before I show the results, here's what has changed (I'll list everything even if it is seemingly unrelated):

Re: TT VME Graphics - Revisited
Looking at your first two screenshots, it looks like the blitter is running a few percent faster ? Which will up the scores on a lot of things...

Re: TT VME Graphics - Revisited
It's actually the other way. I guess I should have named the files "After & Before". So despite the blitter actually being slower, my rig is significantly faster than before.

Odd... maybe its the caches screwing things up ?Atarian Computing wrote: ↑Fri Jul 27, 2018 11:23 amIt's actually the other way. I guess I should have named the files "After & Before". So despite the blitter actually being slower, my rig is significantly faster than before.

Re: TT VME Graphics - Revisited
Is there blitter in any TT ?
There is 2 kind of people: one thinking about moving to Mars after here becomes too bad, the others thinking about how to keep this planet habitable.
