The unusual rhythmic stutter leads to frame drops only when FPS falls between 150 and 210 frames per second.
The unusual rhythmic stutter leads to frame drops only when FPS falls between 150 and 210 frames per second.
I recently acquired a 1440p, 480Hz monitor and noticed some games still lagging even when FPS counters show high numbers. I opened MSI Afterburner with the frametime graph and observed a repeating stutter occurring every 2-3 seconds. The odd thing was that this only happened in certain titles (CS:GO, Deadlock, Apex), while others like Valorant and Rocket League ran smoothly at 480fps. I tested the Nvidia Pendulum demo today and saw stutters only around 150-210FPS, depending on the game. Adjusting the demo’s FPS range eliminated the issue. After that, I logged FPS data for each game. Here’s what I found:
1. CS2 – 240 FPS – Major Stutter
2. Apex – 210 FPS – Major Stutter
3. Deadlock (In-Game) – 220 FPS – Major Stutter
4. Deadlock (Practice Range) – 300 FPS – No Stutter
5. Rocket League – 480+ FPS – No Stutter
6. Valorant – 480+ FPS – No stutter
7. Detroit: Become Human – 140 FPS Capped – No Stutter
8. Detroit: Become Human – 240 FPS Capped – Major Stutter
From this, it seems games near 150-250 FPS often get cyclic stutters, possibly due to GPU issues or G-Sync problems. Adjusting the FPS range in my demo fixed the problem. I’m using a secondary 1440p monitor, which never showed any issues, so it might be limited to reaching that lower FPS band. I’ve tried various V-Sync and G-Sync settings, but the problem still exists. I also experimented with driver reinstalls via DDU, but nothing resolved it. This has significantly affected my gaming sessions. I’m still working through it and have attached photos for reference.
