Tech Report has tested AMD's Catalyst 13.2 beta with a Radeon HD 7950 and it has shown to improve stuttering or frame draw times.
We asked Mr. Dodd whether the changes included in this beta driver would impact performance generally in DirectX 9 applications or only in the three DX9-based games we tested. We also inquired about whether the previously mentioned buffer size tweak for Borderlands 2 was included. Here's his answer:
Basically the fix was different per application (for the DX9 applications) – each fix involved tweaking various driver parameters. In the case of Borderlands 2, yes it did involve tweaking the buffer size.
So what we have in Cat 13.2 is a series of targeted tweaks that appear to work quite well for the games in question. However, Dodd says additional improvements are coming down the pike, including a rewrite of the software memory manager for GPUs based on the Graphics Core Next architecture that should bring a more general improvement:
The driver does not yet contain the new video memory manager. Our intention is release a new driver in a few weeks, which does include the new Video memory manager, which will help resolve latency issues for DX11/DX10 applications.
