PCSX2 r4865支援4core以上的CPU - 模擬器

剛剛發現PCSX2 r4865的commit支援多核的CPU了
如果你的CPU是四核以上
大多數的遊戲有10%~100%左右的fps提升
AMD和Intel的CPU速度都有明顯的增長
有興趣的版友可以抓r4865之後的版本
然後在speedhacks上把
MTVU (Multi-Threaded microVU1) enabled
就可以得到速度上的提升

原作者commit log

Threading VU1 took a lot of rewrites and new code to make possible (MTGS,
microVU, gifUnit...), but we finally got to the point where it was feasible,
and now we've done it! (so now everyone can stop complaining that pcsx2 only takes
advantages of 2 cores :p).

The speedups in the games that benefit from it are great if you have a cpu
with 3+ cores (generally a 10~45% speedup), however games that are GS limited can
be a slowdown (especially on dual core cpu's).

The option can be found in the speedhacks section as "MTVU (Multi-Threaded
microVU1)". And when enabled it should should show the VU thread-time
percentage on the title bar window (Like we currently do for EE/GS/UI threads).

It is listed as a speedhack because in order for threading VU1 to have been a
speedup, we need to assume that games will not send gif packets containing
Signal/Finish/Label commands from path 1 (vu1's xgkick). The good news is
very-few games ever do this, so the compatibility of MTVU is very high (a game that
does do this will likely hang).

Note: vs2010 builds and Linux builds need to be updated to include "MTVU.h"
and "MTVU.cpp".

我本人是沒有去試啦
是去查PCSX2的VFPU指令怎麼做的時候順便看到的
