Hi - I actually wanted to bump this as it’s fully solved.
I used to use Groovy Mame before its low latency option was introduced into baseline and as a Gsync user there was no more need for me to use GM so I moved to baseline. So I tried disabling the low latency option after reading it could cause issues on some games but the problem still persisted.
I downloaded the newest version of GM and all the Rush games run fine now. I even removed my OC profile which I made specifically because of this issue and I’m getting 100% still.
According to Calamity Baseline MAME uses a high precision timer and GM uses a normal one.
The high precision timer is what’s causing my issue. So I guess it’s back to GM. I had a feeling this had to do with a some sort of timing issue because like I stated previously when this issue was happening my processor was not taxed according to task manager and even with my OC removed unthrottled speed does it dip below 100 through attract mode and playing.
