Today, Rudolf released a new driver and app which enables VIA’s C3 CPUs MTRR-writecombining for graphics cards. According to Rudolf, this will increase access speed to your graphics card by 200-400%. That’s a big increase! You can download the driver and app from Bebits here.
Unfortunately, I don’t have a system that uses a VIA C3 processor, but I have been looking at some laptops to run BeOS with which use VIA processors. This would be interesting to try out, so once I have the chance I’m going try testing a BeOS live CD on a laptop that uses a VIA C3 processor with this driver to see what happens, hopefully this method will work. This driver should be very good for those that have a desktop system that uses this processor. So if you try this driver, be sure to report your findings to Rudolf, you can find contact information over at his site here.
