Zbrush works very crashy since R6

ZBrush Usage Questions
#1

Zrush have always been most crashy and unstable soft on my old q6600 , and now it’s all the same on my new i7370 8gb ram. Half of a time I see a faded gray screen in zbrush or just nonstop cycling with a cpu being hardly loaded. Ever touching esc button and Zbrush goes gray instantly. Especially during rendering process.
Perhaps I overburden it too much I am not sure. I never work on a subtool more than 4 mil. No single chance to comfortably work in Photoshop in parallel when Zbrush is open. I can’t even turn Zbrush off while it’s gray and need to push the reset button. The whole comp goes slow like snail while Zbrush is gray.

I honestly thought it was my old pc, a kind of hardware problem but now it’s all the same. R5 worked more or less acceptable although.

Do somebody have an idea what it may be?

It won’t use all of that RAM. Have you been into Preferences to check on/test/set for multi-threading?

Everything is the same on my side. Perhaps I am doing too big files - 25-40mil in total , 3 mil each subtool. When the program do auto saves or something it freezes the whole pc for couple minutes and I can’t do anything on my pc even if I switch to Photoshop.

If it’s too big scene I wonder how people do all those crazy things. While I am working I regularly see that cycling thing on the screen with no apparent reason, if push enything the screen goes gray instantly.

But my main problem not the sculpting but rather rendering. I do environment textures and need to render passes flat from screen in pretty high resolution around 5000px to keep all the subtools details visible in a final texture.

The most crashy thing is normal map pass from normal material. Zbrush just freezes indefinitely with no cpu load and 4gb ram load. Perhaps zbrush 4gb memory limitation is the source of the problem I am not sure.

Clean up files and a defrag might help! Just a thought!

Tried it , no difference. Went back to R5 and it works much better on the same pc.
