Here are some things I did in the last couple days to fix a computer that was basically unusable.
It seems that Superfetch was rebranded to "SysMain" in an update and automatically re-enabled. If your computer is grinding away either the CPU or disk usage while doing nothing, this is the culprit. Disable it in Windows services.
The XBox games bar is suspect. I recommend disabling it now that FRAPS supports Vulkan.
Some features in Visual Studio are making it unusably slow.
In Project settings > Link > Debugging, set "Generate Debug Info" to "DEBUG:FASTLINK" (in the debug build only) for faster linking.
Disable these two settings in the general program Options:
- Enable Diagnostic Tools while debugging
- Show elapsed time PerfTip while debugging
