@OffizierCarl Since the gpu is working fine for rdr2 we can rule out any issues with it. Only reason I wanted to see result from another game was to just rule out stuff like that since all other fixes keeps failing for you. Still a bit interesting if another frostbite game works fine for you like battlefront 2 you mentioned previously.
Your gpu shouldnt be bottlenecked in BFV with the cpu you have.
Could you try something else.
Can you create config.cfg file in your battlefield v installation folder and add these two lines?
PerfOverlay.DrawFps 1
RenderDevice.RenderAheadLimit 2
The first will show you the fps in game (without using origin overlay) and the second will try to put less load on the cpu. you may switch the value to 1 or 3 while in-game by typing the same line (RenderDevice.RenderAheadLimit) in console.
