Flashback 1.1.1
Follow-up to 1.1.0 that removes the last residual Instant Replay freezes under heavy game load.
1.1.0 prioritized the capture pump and audio threads with MMCSS, which fixed the vast majority of the stutter (in testing: 23 freezes → 3 over a 60s CS2 clip). The few that remained came from the one thread still left at normal priority: the WGC frame callback, which copies each frame on the shared D3D11 context. A game spike could preempt it while it held that lock and briefly block the high-priority encode pump.
This release registers that callback thread with MMCSS too, closing the last unprotected link in the capture path. Instant Replay clips should now stay smooth at true 60 fps even when the game is hammering the CPU.
