Regular frame drops [Vive] [many games]
Hello. I noticed today when profiling my Vive game that I was getting a single frame drop about once a second. Popping open the SteamVR Developer's Frame Timing charts I was able to see a pattern of regularly dropped frames. After doing some googling I came across this reddit post.
So I decided to check out some other UE4 games in my library to look for the pattern:
Trials: imgur link
Brookhaven Experiment Demo: imgur link
and my game: imgur link //spike at the end removing focus from the editor window
Is this a known issue?
The issue described above sounds like the result of Vsync. VSync stands for Vertical Synchronization. The basic idea is that synchronizes your FPS with your monitor's refresh rate. The purpose is to eliminate something called "tearing". This can cause frames to drop if the refresh rate of your monitor is not in sync with your fps. I hope that this information helps.
Make it a great day
