DirectX 12 Frame Pacing / Micro-Stutter
What is this error?
Game has inconsistent frame times despite high FPS. Frames are delivered unevenly causing a stuttery feeling even at 60+ FPS.
Common causes
- DX12 flip model presentation issues
- GPU driver frame pacing bug
- V-Sync + frame limiter conflict
- Windows DWM compositor interference
- background process causing CPU frame spikes
How to fix it
- Cap framerate below refresh rate
- disable V-Sync and use in-game limiter
- try DX11 mode
- check background processes

You're getting 100+ FPS but the game feels stuttery — that's frame pacing issues. The frames aren't being delivered at even intervals. 16ms, 8ms, 22ms, 10ms instead of a smooth 10ms, 10ms, 10ms.
Common in DX12 games, especially on AMD GPUs and with multiple frame timing features fighting each other.
How to fix it:
- Cap your framerate 3fps below your refresh rate using RTSS (RivaTuner Statistics Server) — it has the smoothest frame limiter. For 144Hz monitor, cap at 141fps
- Use only ONE frame limiting method — don't combine in-game limiter + V-Sync + NVIDIA/AMD limiter
- Disable V-Sync in the game AND control panel, use G-Sync/FreeSync instead with a frame cap
- Check for background processes causing CPU spikes: Task Manager > Details > sort by CPU. Browser tabs, Discord, Windows Defender scans cause micro-stutters
- Try DX11 mode if available — DX11 has better frame pacing in many games
- Disable HAGS (Hardware-Accelerated GPU Scheduling): Windows Settings > Display > Graphics
- For AMD GPUs: disable Anti-Lag, Enhanced Sync, and Radeon Chill — these can worsen frame pacing
- Use FrameView or CapFrameX to measure actual frame times and identify the issue
When to seek help
If this error keeps happening after trying the fixes above, it may point to a deeper hardware or system issue. Consider professional help if:
- The crash occurs across multiple games or applications
- You see the same error after a clean Windows install
- Your PC is less than a year old (could be a warranty issue)
- You smell burning or hear unusual sounds from your PC
