Causes and Solutions for a slow PC

[GTX 1050 Ti]

So do you reccoment i turn them down or off just for the tests, and thne turn them back up for gaming ?

Depends on your goal. Different games will have different behaviour in any case.

Hi, i accidently overclocked my gpu by 600 mhz for a week, my bpu seems a bit slower now. is there a way i can fix this or is it broken

2D was fast in the year 2018 and early 2019. But is slower now.

Problem:
Microsoft, Intel and AMD have made patches to the O/S and CPU microcode to fix the Spectre & Meltdown class of security issues
https://en.wikipedia.org/wiki/Spectr...vulnerability)

These changes have a performance impact on tests that make a lot of API function calls into the Kernel. (e.g. Disk and 2D). Particularly the advanced vectors and windows interface tests. Performance can be roughly halved.

Solution (Unverified):
If you get the inspectre tool from Gibson Research it can report on what Spectre & Metldown patches have been applied and disable them. This will then restore the lost performance (but also reopen the security vulnerability). In our opinion, the security issues aren't critical for a home user (one user on a single machine). They are more critical in a server environment with multiple users however. So try disabling them and see if it restores the lost performance.

2D was faster in mid 2019, but is slower now.

Problem:
Microsoft have made patches to the O/S to work around security issues. These patches were in September 10, 2019—KB4512578 (OS Build 17763.737)

Like the Spectre & Metldown changes above these changes have a performance impact on tests that make a lot of API function calls into the Kernel. (e.g. Disk and 2D). Particularly the advanced vectors and windows interface tests. Performance was reduced by up to a further 30% (after being cut in half earlier).

Solution:
Don't install KB4512578. Not much of a solution really. Microsoft are aware of the problem, but don't care greatly about 2D performance.
