Hello.
First problem - the normal version of black does not start at all , i have radeon hd 4870 and and windows 7.
process consumes half the memory and processing power, but not start, and i can only kill the process.
Second problem - directx 9 version look good, but in 10-15-20-25 minutes begin a problem -when I paint - there is a big delay...not only delay, look like- draw something and than delay-stop-delay-stop and has not yet finished processing my drawing. Tomorrow i add log, and if needed - video of freeze look like.
Sorry for my english. Thanks.
