MechBFP Posted December 22, 2023 Share Posted December 22, 2023 Reported Version: v0.2.0 (latest) | Mods: none | Can replicate without mods? Yes OS: Windows 10 | CPU: i7-8700 CPU @ 3.20GHz, 6 Core(s), 12 Logical Processor(s) | GPU: Geforce GTX 1070TI | RAM: 16GB I took a rocket and landed it in the ocean. I then went to the video settings and noticed that if i change the VSYNC setting my FPS significantly changes, but not how you would normally expect for a VSYNC setting. Note I have a 144HZ GSYNC compatible monitor and it is configured to use GSYNC. I run the game in full screen mode. When I have VSYNC off I average an FPS of 66 FPS in this scenario. When I have VSYNC on I average an FPS of 80FPS in this exact same scenario. Turning VSYNC on and off repeatedly reproduces this behavior 100% of the time. This is a significant difference and turning on VSYNC should not be causing this large of a performance increase. Included Attachments: Link to comment Share on other sites More sharing options...

Niko_Dragovich Posted December 22, 2023 Share Posted December 22, 2023 (edited) I tried with my RX 7900 XTX with a AMD FreeSync monitor 165Hz and I don't have any difference, same fps with and without vsync. Maybe the NVIDIA GSYNC is working better than AMD FreeSync ? If it's working for you (and some others users maybe ?) it's a good point !

Make sure you don't have VSYNC enabled or disabled by default in your graphics control panel (either globally or specifically for the game), otherwise the in game setting won't do anything. It should be set to "Use the 3d application setting" or "application controlled". Edited December 22, 2023 by MechBFP Link to comment Share on other sites More sharing options...

When I'm in the water, I'm at 130fps with and without VSYNC and when I'm in the VAB, I'm at 180fps without and 165fps (Because 165hz monitor) with VSYNC active.

At that high of an FPS you are likely CPU bound, not GPU bound, so that would make sense. Alternatively AMD cards don’t have the same issue.
