Black Shark 1 runs OK on my system, but when starting mission on BS2, it crashes to desktop of 256 colors, lowest resolution and then frezes so PC reset is needed. AFAIK, nobody reported this issue.

I tried newest GPU driver, older one, 3GB switch, reinstall. PC runs IL-2 smoothly.

AMD X2 270
4GB RAM
Nvidia 8800GTS 512

Thanks for advice!

Black Shark 2 has in-game graphics options not available in Black Shark 1. I noticed that your graphics card is a little old and maybe it can't run some of the newer features. Maybe HDR, TSAA, MSAA?

Lower everything and start from there. For me, the big killer was texture quality and setting my 32bit machine to use the 3GB limit. Details for that are in the readme in the Black Shark folder.

I have found out that the killer was the "full screen" check. Now it runs somehow with crappy fps (does not matter what settings). I just read on ED that in-game AA/AF settings should be preferred to Nvidia Control panel so will give it a try. Thanks for answers.
