I don't suppose the R128DMA() call per se imposes such a high load? No, I also tested it inside R128RMA (for the cases DMA is working) and inside the "if" cycle for cases it isn't. It is not (directly) R128DMA that is causing this, or memcpy, but as these functions take a lot of time to complete (about 10ms for DVD-sized picture), I guess it is something that asynchronously does a busy loop waiting for R128PutImage to complete. But why a wisely placed usleep seems to (mostly) cure the symptoms remains a mystery to me.

Especially for you I did as requested, X eats rougly 50%, i.e. no change.
