AMD Framepacing Catalyst 13.8 driver examined with FCAT




AMD released a Framepacing Catalyst 13.8 Beta driver which we examine with FCAT. In our recent FCAT benchmarking article from April, we discovered that AMD Crossfire suffers badly from a phenomenon called micro-stuttering. A problem that has been known for years and something both AMD and NVIDIA have had. NVIDIA solved their issue starting with Kepler based graphics cards. However since a new technique called FCAT was introduced, a whole lot of micro-stuttering was exposed for AMD, putting them on severe pressure to release a fix for this. Today is the day that we look at AMDs Catalyst 13.8 Beta frame pacing driver and examine the latest games to see if AMD has made progress.

"This first 13.8 beta only supports framepacing in DX10 and 11 games and is compatible with Windows Vista, 7, 8 and 8.1 in the first phase"
Sure 8.1 is supported? Windows unable to detect driver package under installation.. Windows refuses to let me manual install from .inf from device manager.

No 8.1 is not yet officially supported. My grammar checker added that as he assumed 8.1 would be supported. Fixing.

I wonder how the 7990 compairs to 770 SLI as the 690 is hardware based framepacing and the 7990 is software based as 770 SLI is overall impresive results a little fine tuning to get rid of the runt and dropped frames and AMD will have something. Bravo AMD bravo.

680 and 770 have hardware for frame metering, as 690. Tom Petersen of Nvidia has confirmed that in his video with pcper.
Epic review Hilbert, as always.

I still don't fully understand how this works, but if it's an improvement...
