Distributed.net does NOT play nice with gaming-sources

Since "nice" apparently has no effect in gaming-sources, dnetc ends up behaving like a regular process no matter what you nice it to (the --priority option nices the process). The effect is that it gets a lot of the CPU time that it should be giving up to other processes.

glxgears with dnetc: 970 FPS
glxgears without dnetc: 1840 FPS

So don't use distributed.net (and probably SETI@Home, etc) with these new gaming-sources kernels! Anyone have any idea how this problem could be solved?

I was experiencig the same problems with gentoo-sources. -> Now, I use vanilla and I'm happy...

I think it's related to the preempt. stuff... :-(

It happens with seti@home as well. When I'm compiling something big, or play games, I turn seti@home off. It usually steals around 50% of the cpu.

Using the vanilla sources it only steals 14%, but that's enough for me to turn it off when playing games. It doesn't bother my to wait a little while longer when compiling though.
