Thank you so much for your GPU Tuner Patches! Most excellent and well done. Although mileage is going to vary depending on operating system, CPU, graphics card, and driver here are some stats for my system that I calculated based upon as standardized bench marking I could do (though imprecise as there was no set "track" for testing - but these were formulated by 3 run averages of each condition in identical weather, identical enemies, doing basically the same thing each time over 3 min frap logs):
Comparison to PR v2 (Quality)
PR v3 (High): - 10.99% fps average VonS v1.2: - 1.01% fps average VonS v1.3: - 2.54% fps average
So for me, both VonS versions I tested (sorry, didn't do v1.1) were better than PR (High) and quite close to PR (Quality), while looking better overall. Also, imho, VonS v.1.3 looks the best compared to VonS v1.2 and is only a very minor sacrifice in fps (at least for me).
