Just dropping an update here since people have been quite critical of my setup, I'm clearly not an IT expert either
I was reading from CPU-Z which seems to give the base DRAM frequency not the effective clock rate in a dual-channel environment. Checking in performance monitor my RAM was at 2400MHz which led me to realize my XMP reverted to disabled, so enabling that bumped that up to 3000MHz which slightly increased FPS in the trouble areas.
Also, I realize my CPU is an older generation, but replacing that isn't as simple as slotting in a new CPU(need new MOBO and probably new RAM) so that's why I have a much higher tier GPU as it's plug-and-play. Incremental upgrades, you know?
tl;dr
Enabling XMP in the BIOS did slightly alleviate the issue (getting 57 FPS at the same area vs 47), so if anyone is having similar issues this might be an avenue to look into.
