I have recently upgraded to a GTX 980 from a 770 and I haven't noticed any performance increase. I find that on a bare map with not units, looking at a town drops my FPS to 40-50 and I getting perceivable micro stutter and tracker becomes jerky. I have checked my system using afterburner and during the periods of low FPS, the GPU is running at around 50% and the CPU is running at 50-60%. I have attached my settings.
I have also noticed that I only get this issue when flying very say 500ft and when fly over the same point at 600ft+ I get a solid 60FPS.
I don' have this issue in DCS 2.0. I also don't use tree shadows using mustang's mod.
I am using full screen (alt+enter) and I have tried both live and OB with fresh installs and I get the same problem.
I have also tried with no mods and I get the same issue.
What could be causing this as neither my GPU nor CPU are maxed out?!
Please help.........
UPDATE: After more testing I think shadows are the issue. If I turn shadows off I get a solid 60 everywhere but if I have any form of shadow (low, medium, high or ultra) I get the same FPS drop and the magnitude of this drop seems to be the same regardless of whether I am using low shadows or ultra shadows. Is this normal?!
I am not willing to fly without cockpit shadows as it would spoil the experience for me and I can't remember experiencing these issues with my 770 2GB.
