http://emu.crimsonrain.com/2009/07/pcsx2-svn-r1575.html PCSX2 SVN Changelog: r1570 microVU: more regAlloc work... r1571 GSdx: - Automatic texture filtering should be ok now, occasionally point filtering was used. Tested it on the ps2 and figured with no mip levels LoD and minification settings are just ignored altogether. - Also run a few tests on the gather instruction with the reference rasterizer and found a fatal flaw with it. It returns the four samples for bilinear sampling (in a funny order, which isn't documented of course, x = bl, y = br, z = tr, w = tl), but there is no way to guess which four were selected exactly. Due to some hidden rounding error it might grab different texels than I would when calculating the position of the upper-left texel, of which the fractional part is be used for the interpolation. When the texel positions do not match it leaves annoying discontinuity errors. Oh well... r1572 wxgui: Improved threading model used by the log window, plus a few minor fixes to main window startup/shutdown code. r1573 microVU: - Finished implementing regAlloc. Sadly the speedgain wasn't great (0%~2% in the games I tried). I think the speedup should be bigger with a CPU that supports SSE4.1, but I don't have one to test :p r1574 microVU: tweaking/testing some stuff... r1575 microVU: fixed a bug in my clamping code from r1568. Fixes TOTA invisible characters when clamp-mode set to 'normal' -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 59.126.238.100
