"Issue I'm having is whenever there's a ground battel going on and i'm up in the air, a few 10 to 20 miles away, as soon as my screen has that ground battle in sight, GPU utilization drops to single digit percentages. Sometimes like 10 or 20%. So basically, it's getting bottlenecked by CPU. Also, CPU always sits at about 30 to 40% so evidently, it's only using about 1 to 2 threads even though I have 4 cores. DCS really likes higher frequency CPU because since it only uses those 1 to 2 cores, the higher the frequency, the more it affect framerates. Otherwise, graphical settings are basically all on high or ultra, Anti Aliasing set to 16x (There is basically no performance difference AT ALL whatsoever between the settings) and depth of field is off. Vsync is off.
When the performance tanking happens, I drop from about 70 to 80 fps down to 20 or sometimes even 15. If I'm staring into the sky or I'm simply at a very high altitude, i easily get about 150 to 180. "
That sums up well my issues, game is just like that here too. Terrible frame drops.
