February 16, 20188 yr I did a fresh install of P3D v4.2 and now it appears the vsync no longer works. While engaged, the fps jumps from 42 fps down to 9. I also see more stutters with more pausing. I am operating with a 4K monitor with a refresh rate of 30. With 4.1 the vsync kept the fps at 29-30 with a smooth experience. 6800K oc 4.3, SSD, 4K monitor, GTX 1080 ti Beechcraft Sundowner
February 16, 20188 yr Are you using the latest version of FSUIPC by chance? 123 causes pause/stutter/menu issues in 4.2 122 works fine. You can downgrade with no issues if that's the culprit. Ilya Eydis, PPL, ASEL
February 16, 20188 yr Moderator FWIW, I have a 4K monitor and use TrackIR - I lock at 20 and do not use Vsync. No issues at all. Vic RIG#1 - I9 14900K MSI Pro z790 RTX 5070Ti 40" 4K Monitor 3840x2160
February 17, 20188 yr Author Vic- I tried locking to 20 fps and the sim was not fluid, like it was using vsync in V4.1. I wonder if V4.2 broke vsync? Beechcraft Sundowner
February 17, 20188 yr FYI. I have a 3770k and 780GTX with only 3 gb VRAM and a 30hz 4k monitor. I just installed P3Dv4.2 and have no addons installed yet. Turning on Vsync with or without triple buffering drops my FPS to a steady and smooth 30 just as it did in P3Dv4.1.

February 18, 20188 yr Same FSUIPC that used with 4.1 here and took off from FT CYYZ smooth and no stutters. FT CYYZ always gives you a FPS drop but once above FL 50 everything smooth on first flight.... Alex

If it's works, he will know it's because of 4.2, if not he will know it's something else and not 4.2 It's very easy (few minutes) to go from 4.1 to 4.2 or 4.2 to 4.1 so it's a start point for troubleshooting..

Mike Mike- Unfortunately I removed 4.1. I did a clean re-install of 4.2 and the same issues. FPS jumps from the low 40s to single digits with Vsync on. It is a bit of a mess. Beechcraft Sundowner
February 18, 20188 yr Author New development. This behavior seems to manifest itself only when using Orbx Germany, both North and South. Perhaps this is an Orbx incompatibility with 4.2. Beechcraft Sundowner
