Just got a new computer (i9-9900k with a RTX 2070 Super) and I find that the adaptive vsync with half refresh trick still does the best job with getting smooth frame rates, but with the latest nVidia driver (436.30), setting Vertical Sync to 1/2 Refresh Rate and Vertical Sync Tear Control to Adaptive doesn't cut the frame rates in half to a smooth 30 fps.
Is this true for others that use this setting with the latest nVidia drivers? I read a few posts where others indicated the same thing.
I ended up having to use the Frame Rate Limiter set to 30.5 to get the smoothness.
For those who are curious, my new computer plays CMx2 better by allowing me to increase the 3D Texture Quality to Excellent on most scenarios using the adaptive vsync trick. My old i7-920 at 4 Ghz with a GTX 970 only allowed me to use Balanced or Improved on most scenarios. So the increase in performance is good, but not breathtaking with the new computer.
Steve has mentioned to me that he intends to put these games back into the Store. However he always seems quite busy and this, I assume, is a lower priority. The CMx1 games (CMBO, CMBB and CMAK) WILL eventually be in the store, but when is anyone's guess.
