I have experience suddenly frame drop random 2s freeze during fps games like rainbow six siege, apex legends, csgo, 3A like GTA5. Suddenly frame drop like running 178 fps for a really long time and then drop to 100fps. 2s freeze like graphic is freeze for 2s and everything normal. When it happens, I put firefox in the background let static web page opened, youtube video playing(1080p) with firefox picture in picture or open it in a new tab.
Method I use to debug:
1. Fresh installed system: windows 10 22h2, windows 21h2, 22h2, 23h2.
2. Motherboard driver: fresh installed system with every combination of driver installed. Driver come from asus website, iobit driver booster, or 360 driver manager.
3. Multiple monitor: I have three monitors. I also tried every combination of these three monitors.
4. Usb device: I am not using any usb dock/hub. I also tried plug or unplug all of them.
5. Keyboards and mouse: I have three keyboards and two mice. Test with all of them. I also swap to new pcb for my keyboards.
6. CPU,motherboard, ram, SSD, HDD, Ethernet cables, usb cables: I order new parts and test them. I test both ram with memtest86, all passes.
7. windows activation: I tried three ways to activate windows.
8. GPU: I have a 2080s and 4090: I tried both gpu and test different version of nvidia driver (uninstall with DDU and install without nvidia experience app).
9. Temperature: I have custom loop connect to my cpu. under R23, p95, max package temp is 88C. GPU max temp is 72C under furmark test. I do these tests both, and I use a meter to track power, total power never exceed 600W and I have a 1000W PSU. I also check all power cable is not exposed its wire and normally bent.
10. App: I only install necessary driver installed and steam and firefox. And bios is XMP on/off, Multicore enhancement on/off. I test them both. And it doesn't help.
11. Different version of firefox. I tried 118, 119, 120. I also tried refresh firefox, disable all extensions, default setting for firefox. (I have experienced poor firefox performance back to firefox 107 at first release of windows 11 22h2).
I love to use firefox. I am software developer too. If possible, I can assist test this.
