Having Instant Replay enabled causes subsecond stutters for me in games, while everything is running smoothly with it disabled.
I have ensured GameDVR is turned off.
This is easily and reliably reproducible with Unigine Superposition (4K Optimized).
Feel free to ask for more specific information to resolve this issue.
