This looks to be a hardware bug, size of dangerous RAM depends on pre/post NV40 architecture, bug exists for both FIFO channel assignment on the fly, and DMA command buffer existing in cardRAM. If there are still users outthere using PIO acceleration and 3D they have a good chance of having working concurrent overlay as well, as the fifo-assignment bug turns up with PIO acc as well. Note: the bugfix is still in test: confirmed on TNT1 only for now. |
