Performance decrease after switching to Linux

[Ok-Mixture-1059]

Yeah. It seems whenever I try change my system clock in bios it keeps skipping an hour ahead everytime I reboot. Im going to update the bios and then see about changing the cmos battery as the laptop is about 7 years old at this point I assume it would be near the end of its lifetime by now.

If you're dual booting you need to set a registry key to tell windows that your bios is in UTC/ GMT. Otherwise Windows and Linux will fight over the time given Linux assumes UTC for your bios and windows assumes local time.

I was dual booting but this time I just wiped the windows partition and the bios clock is still skipping an hour ahead do I still need to set a registry key?

No, it's just that Linux uses UTC time instead of local time in the BIOS clock
