@BairRaisin007bf2042 is very cpu intensive game !
I do not know if your tv could be/is an issue !
What i can see is , youre gpu is PCIE3.0 , newer gpu cards are 4.0.
I also see your use a HDMI cable, is it a good quality cable ? not an ACTION cable?
If your tv supports DP (display cable) then buy a good quality DP cable , version 1.2 min. or a 1.4 cable (is able to send more data at a higher MHZ !).
It can also be an out of date Bios version, or other hardware that hold back performance of youre system (external devices, low performance CPU / MEMORY).
Maybe its a combo , but that is what ya need to investigate.
If ya find the partnumbers from youre memory , perhaps ya can boost memory and cpu a bit more (OC).
Sometimes it can also be heat , that throttle down CPU , GPU and or Memory !!! Ya need a very good cooling, youre cpu is probarly running at 100% (1 or more cores/threads)
Download HWINFO64 PORTABLE version, run it with SENSORS ONLY enabled , and check Temps + Mhz during game play !!
Keep us update
Cheers
PS a CLEANBOOT will minimize programs running in the background, so less stress for cpu/memory and more power/performance for other stuff , for BF2042 example
