- Found that black screen caused by low latency Vsync. Disabled Vsync = no more black screen, boot properly.

- Also, "Standard Vsync" make the FPS drop from 50 to ~45 with very bad sound, unless at least "Cycle Exact (DMA/Memopery access)" is selected, which in turn slow down the emulation considerably, even with "JIT" enabled and "CPU Emulation speed" set to "Fastest possible".

In other word, if you want to watch demos that requires a 040/060 and want fast FPS and clean sound, you currently can't use any VSync at all. I already use "Cycle Exact (Full)" for anything Amiga 1200 or lower that runs standard Amiga software and games. The problem is with Amiga 3000 and 4000 and accelerator boards where you need all the speed you can get AND want to have Vsync enabled. "Cycle Extract" is not an option here.

NOTE: I'm launching Winuae with the following batch file using SetRes to set my monitor from 60Hz to 50Hz and back to 60Hz when I'm done:

"C:\SetResSingle_V2_3 GPL3\SetRes.exe" h1680 v1050 f50
START /W "" "D:\Commodore\Amiga\Emulator\WinUAE\winuae64.exe"
"C:SetResSingle_V2_3 GPL3\SetRes.exe" h1680 v1050 f60

NOTE 2: I case this could be an issue, I'm using 3 X monitors, without the Nvidia surround option. Windows 7 AERO is enabled.

And just to make it clear my rig is not the limiting factor:

2500K @ 4.7Ghz
16GB RAM @ 1866Mhz
2 X Crucial M4 SSD in RAID0
660 GTX @ 1.3Ghz
Latest OS / hardware drivers installed

I hope this help,
