I just compiled a build of powder toy with VC9 (don't have VC10) and copied the inline definitions to some different files. When I compiled it, the CPU usage is always 70%+ on my computer (the official is 30-40%). In general it's taking up the entire CPU. What's wrong??? I can't really run my powder toy... No idea...
thats normal, the latest source that you compiled has some multi-threading for the gravity, which seems to run even if it isn't used. I'm sure this could be fixed some, but there is nothing wrong.
