The developers promised that multi-GPU systems will speed up by 11-13% in games based on CryEngine 2. However, we didn’t see anything like that. We didn’t reveal any slowing of the Radeon HD 4890 CrossFireX tandem either, and in resolutions starting at 1680x1050 and up its minimal performance in fact increased a little. So, we can conclude that Crysis and Crysis Warhead fans will not really benefit from upgrading to Catalyst 9.6 driver version.
We have to particularly dwell on a significant performance increase by Radeon HD 4770 in 1920x1200, which hit almost 30%. However, in absolute numbers it only means that the average performance rose from 7 to 10 fps, which is actually of no real practical value for gamers anyway.
Enemy Territory: Quake Wars
We have always included this game into the list of our regular benchmarks for the new ATI and Nvidia drivers, because its engine is based on OpenGL API, which is a pretty rare thing these days.
ATI didn’t promise that anything would improve in Quake Wars and our tests showed that it was indeed the case: the results obtained with Catalyst version 9.5 and 9.6 are absolutely identical.
