ASUS ROG PG348Q 34" GSync at 3440 x 1440 and I'm generally getting 100 FPS at high altitude and 65-75 FPS down low over a large city.
Game Detail Settings On All 5s. Max FPS limited to 96 in cfs3.xml.
I've modified my composite scenery and texture budget files and landclass sizes to minimize stuttering, and to prevent trees and buildings from popping into existence as you draw near enough to view them. (I wish there was a way to do that for clouds as well but their draw distance is hard coded)
AnKor's Shaders and SweetFX (needed for GSync to work)
GTX 980 with 16x Anisotropic Filtering, 4x Multisampling and 4x Sparse Grid Transparency Supersampling (reduces shimmering), LOD Bias -1 (restores sharpness lost by MSAA). Max Pre-Rendered Frames are Application Controlled. Vsync On. High Quality Texture Filtering. Max Performance Power Management. (I've tried 8x and 8x, but it doesn't improve the image all that much, and drags the FPS down about 20 points from 4x and 4x)
AMD X4 955 overclocked to 3.8 GHz with three cores allocated to CFS3 and the forth for TrackIR using Process Lasso.
