Flanker35m - Constant Stuttering Frequency

S!

Spiking and FPS dips. LOG and Track attached. Nothing helps with them.

Some more data on the spiking. And this behaviour is only in DCS, all other games run rock solid.

This is how the in-game performance monitor looks when having NO forced VSync from GPU drivers. Only using in-game FPS limiter set to 300fps and DCS own VSync enabled.

This with in-game VSync OFF, fps limiter at same 300. VSync ON through GPU drivers.

And last image with no VSync whatsoever, fps limiter still at 300fps. Always using same parameters: FW190A-8, Free Flight, The Channel map and fly low over the city at the coast.

And last test with AMD Enhanced sync enabled from drivers, no in-game VSync and fps limiter set to 300. It looks like VSync is causing stutter issues with the game, without it the game is smoother but has some tearing.

And this is how the spiking looks like.
