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

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.

I was hoping to see specific suggestions for CPU score being low. I have just built new PC around 11900k and my score is a very disappointing 19256 against average of around 26000.
I downloaded a baseline to compare but could not see the direct individual comparisons for integer math, prime numbers, CPU single threaded of the baseline.
Is this possible to do?

If your speed is locked to 3.5Ghz, maybe check your BIOS and make sure that you have not disabled Turbo boost?

An interesting new case for slower than expected RAM speeds.
Problem
I use faster RAM, but performance is worse than with slow RAM on a Ryzen CPU.
Solution
The CPU has a power budget and with high speed RAM the power budget is hit, resulting in throttling of the CPU.
Details are in this video

In our opinion this is kind of poor design. What is point of claiming to support high speed RAM if it might slow the machine down overall? Makes getting the optimal BIOS settings overly complex.

And other one
Problem:
RAM got slower in June 2021 on Intel CPUs (in some circumstances).
Solution / Cause:
Intel implemented some (more) CPU microcode changes to work around (more) security bugs.
Details are here
https://travisdowns.github.io/blog/2...-zero-opt.html
Impact is probably pretty small in real life software, but if you are doing regular benchmarks you might notice the machine getting slightly slower.

Problem:
2D score are really low even on high-end pc
Solution:
Disable G-SYNC in monitor not just nVidia control panel
I went from main score ~2300 to ~7000!
