A few days ago, the 14.4 Catalyst RC drivers (content complete but pre-WQHL certification drivers) were released. I was curious since the changelog lists various improvements to the way Crossfire X is implemented in the games that would need it at high resolutions: Crysis 3, Battlefield 4, Thief, Titanfall, etc.
Here are some notes with my current nMP. First, the specs:
Stock 6 core @ 3.5ghz
Stock dual D500 3GB
16GB RAM (although that won't really enter into the performance equation)
Windows 8.1 x64 (only flavor of Windows you can run on the nMP so it goes without saying)
So:
1) Crysis 3: a MASSIVE improvement running at 2560x1440 with Very High Settings. The listed fix was for the frame-pacing, and now even with those options cranked up, it is a very playable 30-40fps in large environments and 50-55fps in corridors and inside buildings. Reducing shadow quality or particle effects will get you closer to 60 fps. This game truly makes the best of those GPUs
2) Battlefield 4: A noticeable improvement. The game was already playable at a constant 40-45fps with severe drops during multiple explosions or with heavy vehicle combat on-screen. The drops seem to come less frequently, and are less severe. Drops on 14.3 were often to the single digits, where it now seems to deep into the high teens.
3) Elder Scrolls Online: a few fundamental issues more related to its engine, but otherwise really smooth gameplay. 60+ FPS even during peak hours in towns.
I'll be getting my hands on a copy of Titanfall to test out this weekend. All in all, this is really starting to feel like a $4,000 workstation that can easily double as a great gaming PC. For the 3 months i've had this machine, I thought I made the wrong choice by skipping the D700 upgrade, but with these new drivers and hopefully future ones improving upon it, the performance needed to comfortably game at high and often max details at the Thunderbolt Display's native resolution is really there.
