The PC version of id Software's Rage is making headlines lately, but perhaps not for the right reasons. Earlier today, Nvidia put up a lengthy blog post on GeForce.com to address some of the texture fidelity issues Rage PC players have complained about.
Nvidia points out the the game "dynamically adjusts detail levels at all times to try and maintain an optimum balance between performance and graphical fidelity," but goes on to say that, based on its observations, "there does appear to be an error or two with the Auto-Balancer." Namely, the company says the auto-balancer is overly conservative and uses lower texture resolutions than it should.
Until the appropriate tweaks are made, users can force the use of high-resolution textures manually. The procedure requires a decent amount of video RAM (Nvidia recommends 1.5GB), but it doesn't take much effort—simply create a file titled "rageconfig.cfg" in Rage's "base" directory, and fill it with following:
Judging by the screenshots in the blog post, the 8K setting is noticeably sharper than the "default" setting Nvidia used, which seemed to default to a megatexture size in the 5-6K range.
Of course, your mileage may vary depending on what GPU you're using and how well the auto-balancer is working for you. It sure would be nice if the game didn't have such kinks to begin with, though.
