The same issue here:
- FPS jumps from 47 to 27 back and forth (only partially settles down when in the same area for long time)
- Stuttering in synch with the above jumps (very unpleasant)
- Happens only in Su-25T cockpit view (TP-51, Ka-50 and external views don't have this issue)
Tested with DCS World 1.5 latest build on HDD and SSD. With a page file and without one.
