Hello Tom,
Thank you so much for reaching out, I am Udit an independent advisor, and I am glad to assist you today with this issue.
You've done solid troubleshooting already. Since the issue started after moving to Windows 11 23H2, it's likely a compatibility or background process issue. Here are key things to try:
- Disable Memory Compression Run this in PowerShell (as admin): Disable-MMAgent -mc > Reboot
- Check for Driver Latency Use LatencyMon (https://www.resplendence.com/latencymon) to detect bad drivers (network/audio/video).
- Monitor CPU Throttling Use HWiNFO64 to check for thermal or power throttling. If temps are high or clocks drop, repasting the CPU might help.
- Turn Off Hardware GPU Scheduling Go to: Settings > System > Display > Graphics > Default settings > Turn off Hardware-accelerated GPU scheduling
- Consider Downgrading to Windows 10 Your i7-4770 runs better on Win 10. 11 is optimized for newer CPUs.
Let me know if you want help with rollback steps.
Regards
Udit
