what expected from tweaking vu skip

cmkannan · May 11th, 2008

what's the different things expected from tweaking vu skip?
also is vu skip just skipping frames to get normal speed
then i think it's better to add option to select the frame to skip

Well i geuss, once you reach a state where sound plays faster/skipping video than must tweak that func!!,,,,Time for a FRONTEND

it automatically chose how much frames it skips, but that does not always work correct

cmkannan · May 12th, 2008

will implemeting the option mentioned above be useful?

why none is responding?

Because people ran out of things to say?

One of the types of frame skipping I quite like is the one dosbox uses, though it doesn`t refer to fps, it more refers to cpu cycles. Anyways the way dosbox does it, is auto detects the best cpu cycles to run the game at, based on the users computer and the game itself. Ofcourse this doesn`t always work, but a fair few games run excellently via this method. And if the game doesn`t run quite well, or you want it to run faster then you can increment and deincrement the cpu cycles via hot keys on the keyboard to make the game run faster or slower. Quite a nifty feature.

Obviously though, dosbox is a emulator for the old dos 6.0 from long ago, and pcsx2 is a ps2 emulator, so entirely different. But be nice to have a similar kindof frame skipping.

I tested around 10 games and the only one that got a speedup - from 40 to around 60 fps - was Fight Night Round 3 (Q9450 3,4 ghz cpu). A side effect was that some of the cutscenes were black and I had to push buttons to skip them.

Every other game I tried did not benefit from VU skip or crashed when it was on.
Maybe other users could give other examples.

I tested VU skip in Grandia 3 and it gives plus 10-15 fps in battle but very often a black screen appears after battle

Changing the interlace mode usually fixes that.

I think it's due to not full support from GSdx plugin, does it work with ZeroGS?

domat7 · May 16th, 2008

I've tested:
Battle Stadium D.O.N
Naruto Uzumaki Chronicles 1
Naruto Uzumaki Chronicles 2
Naruto Ultimate Ninja 1
Naruto Ultimate Ninja 2
Naruto Ultimate Ninja 3
Naruto Shippuuden Narutimate Accel 1
Naruto Shippuuden Narutimate Accel 2
They all run faster(or rather normal) with VU Frame Skip. The only problem is the well-known flickering.

Try pressing F5 when that happens
