Realbench massive score drop after 1803

4770k on Asus Maximus VI Hero, 1603 bios, EVGA 1070 SC, 16Gb TridentX 2400.

Total of about 12 runs before the Win10 1803 update, average ~106k.
After 1803, roughly 10 runs average 97k.

After 1803, I used DDU to uninstall graphics drivers, updated to latest, still averaging 97k.

The only possibility I came up with was that Haswell was impacted harder by the Meltdown/Spectre patches (my bios is a couple years old, but the latest on the ASUS website for my board...so no firmware/bios spectre mitigations).

Any thoughts?

I appreciate the question, as benchmarks don't always equate to real-world performance, but two things:
-It's not necessarily the absolute score, but the relative distance between scores before and after that really bothers me
-Second, it may sound a bit petty but I would like to increase my Realbench ranking (as a matter of personal pride if nothing else).

I have noticed a slowdown on all CPU intensive benchmarks, less so on GPU intensive ones.

Just wondering if other folks on older platforms like mine have noticed any particular cpu issues since 1803.
