Tear-Free Acceleration For ATI EXA, Xv
Written by Michael Larabel in AMD on 16 July 2008 at 08:02 AM EDT. 120 Comments
For those of you that have been using the open-source xf86-video-ati driver, need we remind you of its rapidly-improving state and feature set? One of the latest additions to this open-source ATI driver that supports the old ATI R100 graphics cards up through the new Radeon HD 4800 series (RV770) is tear-free acceleration. The current implementation of this tear-free acceleration is for EXA and Textured Video (X-Video) and should eliminate any "tearing" issues that some users experience. This code isn't yet found in the master branch of its development git repository, but can be acquired through the vsync_accel branch. Alex Deucher, the mastermind behind this latest code, has described this improvement on his blog.
