TUTORIAL: Advanced anti-aliasing and frame rate fix for Windows 8.1
I'm not sure if this is the place to put this, but I just want to provide tips for users having trouble with microstuttering in this game when running Windows 8.1 and trying to find enhanced methods of anti-aliasing.
To fix microstuttering, you will need to download and install a program which will allow you to save CPU affinity settings to applications. Create a new rule for this game and set the CPU core affinity to enable all except one core. There seems to be an issue with one core hijacking the CPU and running at max load, bottlenecking the other cores. Disable the offending core in the process manager program (if running a Core i7 CPU, disable both the physical core and its logical core) and save the application profile. In my case, I disabled the first core and its logical counterpart, so different systems may need different core assignments.
Since this game has no in-game anti-aliasing settings and the edges are rough, the easiest way to counter it requires an NVIDIA GTX 600 series or later video card with GeForce driver 344.48 WHQL or later. Enable the 4x DSR factor in the NVIDIA control panel to render the game in four times the resolution of your monitor (up to 4K on a 1080p monitor) and enable high-resolution textures in the game's graphics settings. The result is smoother-looking edges, though still not up to 2014 standards. Please note that a GTX 670 or better video card is required to run the game at 60 fps maxed in 4K resolution. If running an older NVIDIA video card or an AMD video card, then try enabling different forms of anti-aliasing in the NVIDIA control panel or AMD Catalyst Control Center. Forcing anti-aliasing this way may result in heavy GPU usage, so be sure to enable the anti-aliasing settings which best fit your hardware. If you have a high-end NVIDIA card (GTX 770 or better), then enabling anti-aliasing 8x standard setting and 8x transparency supersampling at default resolution will yield better results than using DSR.
