reduce most everything. TLOD will give you a hit. OLOD as well (+/- 20 will not make much a visual difference). Trees, pre caching, photogrammetry, AI all affect performance.
You’re otherwise okay. Check on the next highest settings (high end i think?) and see what happens. Also might not hurt to let us know what resolution you’re at.
In the end though, you may need a CPU upgrade anyway as that’s a 6 year old chip.
