I've been using Mandrake 10 w/ X4.3 on both a TPT40 and R40. Both have a Radeon 7500 video card. Seems to work fine for me. glxgears reports >175fps in both cases. Does anyone know whether there is any advantage to installing the new ATI proprietary driver: http://www.ati.com/support/drivers/linux/radeon-linux.html?type=linux&prodTy ? What will it give me? TIA Paul
