Fast Depth != early Z. Early Z is zcomploc.

Apparently it kinda is the same in the dx9 final branch. http://code.google.com/p/dolphin-emu/source/detail?r=5349c64e1a68a131cf01051ec679781a6dc75b61&name=DX9-Final

o_O. What a weird hack...

I'm using fast depth id dx9 as a way to enable/disable early z from the user side, is just a temporal solution while improving the configuration menu.
I will check the source of the slowdown can you tell me the exact revision that slow downs SSAA?

I found it. The slowdown first occurs on DX9-Final-4.0-14-x86. It doesn't occur on DX9-Final-4.0-12-x86. There is no 4.0-13. So whatever change in 4.0-14 causes it.

thanks for the help i will try to fix it asap

Also, Nintendo screens flashing of Fire Emblem: Radiant Dawn first occurs on DX9-Final-4.0-121-x86. It doesn't occur on DX9-Final-4.0-120-x86.

ok traced back the slowdown to the source and is tev-fixes-performance, the slow down is due to the modifications needed to increase acuracy in tev, it only affects ssaa 9x because the amount of pixels that are calculated, so is a trade of acuracy vs speed.

Thanks for the information. It's unfortunate. I like to use 9x SSAA. Accuracy is all well and good but in this case I don't see any visual differences but the performance drop is quite noticeable.

I moved the off-topic posts to a new thread but something went wrong and I can't find the splitted thread anymore. BTW, this one is for DX9-Final tests/bug reports. If you guys want to ask for old builds, ask elsewhere and be warned that we don't support anything older than latest stable release in the forums...
