Reduced performance on Ventura OCLP 1.4.3

I own a unibody mbp 2012 15 inch with the 2.6ghz i7, this processor normally scores 800 single core 2800 to 3000 multicore but on Ventura it's only doing 500 single core 2000 multicore, is this a known issue with OCLP patched devices? The Ventura installation is 1 week old it's had more than enough time to index and sort itself out, what can I do about this?

Thanks.
