Can someone please help me. When I select half refresh rate(trying NVidia control panel or inspector)my fps still goes to 60fps. My monitor is 60 hertz. Other games I have tried that work properly and cap the fps at 30 are DCS World, X-Plane and Aerofly FS. I'm not sure why P3D doesn't work with adaptive v-sync half refresh rate. Anyone have any ideas? This is driving me nuts as maintaining 60 fps is difficult and I get massive stutters trying. If I lock the fps to ANYTHING I get massive stutters, the only smooth sim experience I get is with v-sync on and that is only smooth when I can maintain 60 fps. No tweaks in config other than AffinityMask 84. If I disable v-sync in game, I get wildy fluctuating fps but usually maintain above 60 as long as I don't lock fps. I would love to have adaptive v-sync work so I can run off of 30 fps with unlimited frames on and v-sync on. That is the only way I can see simming with any reasonable settings and fluidity. This is driving me nuts!
