RE: [blog] Threading VU1
Again, not necessarily true. There are quite a few 3D games were I saw a boost on my i5 laptop (2 cores, 4 threads) but the difference was lower (percentage wise) than my AMD x4 real cores. It really will depend on the game, and even certain scenes in each game. There are some games even on true tri or quads that get slower results with MTVU.

RE: [blog] Threading VU1
Maybe i'm missing the argument here..

But Rogue Galaxy gets a massive speed up with MTVU on (the VU% is often around 30% for me)

I wanna say Dark Cloud got a boost as well. But i didn't play that before my new video card. So i could be wrong.

RE: [blog] Threading VU1
For some reason *got an info from member on this forum* intel quadcore Qxxxx series has negative impact in certain game where is on next quadcore intel i series/AMD Quadcore has opposite (positif) impact for MTVU hacks. Anybody can give explaining for this??

RE: [blog] Threading VU1
It's a speedhack that doesn't have a constant speedup and behaves differently depending on the hardware Tongue

the person with the AMD cpu likely has a better GPU than the person with the Qxxxx.
slowdowns on a quadcore are due to the GS thread or GPU limiting the game.

RE: [blog] Threading VU1
FFX and FFX-2 are showing a great speedboost when using MTVU on my i5 2410m (Dualcore)
But on my C2D E6700 there is no speedboost at all, ok there is a difference of ~2-3fps but it's fluctuating a lot.
So the HT feature of the i5 might do the trick Wink

I think, that positive impact cpu i series from MTVU is be caused from new technology exclude Hyperthreading. If you want to test hyperthreading impact in MTVU then try with ON/OFF to see how much impact can get with it.

RE: [blog] Threading VU1
How do I disable it?
My ION based PC has such a option in the bios but my laptop doesn't.

RE: [blog] Threading VU1
I think only desktop cpu we can test at moment since that option has in bios mobo.

I don't know a whole lot about threading, but that sounds like an interesting way to get around thread synchronization. Is this an optimal solution, or simply a workaround to get MTVU working?
