Framerate dips prevent me from being effective in air to air combat, often. .
I would be curious to know what your PC specs are and what graphics settings you are using in DCS because I don't get any noticeable drops in frame rate during air to air combat. I have an AMD 5950X with 32 GB RAM and an Nvidia 3090 and I have most graphics settings in DCS set to maximum. I am however playing the game on 1920x1080.
Well I play online, so that may be a big part of the drops. Even a slight dip below a butter smooth 60+ is enough for my terrible eyesight to lose a grey dot in a sea of grey dots.
7700k @4.5ghz + 1080 GTX + 32 gigs of RAM until I get back to my Arizona PC which is 12900KF + 3080 Ti FTW3, so 7700 for the time being.
Online servers such as Engima's Cold War can often see sharp drops at random times. When in the cockpit of a Mig 21 with horrible visibility, this exacerbates the problem.
Sometimes I want to yank my 50 inch television off the wall and plop it onto my desk. My 27 inch is nice, but the 50 inch is soooooooo big and makes the dots easier to find.
