DCS BETA 2.5.5 = 45 (60*) FPS (SSD drive)
DCS Stable 2.5.4 = 45 FPS (Normal 7200rpm disk drive)
ASW OFF using Occulus tray tool.
* If I touched nothing and ran the test straight and level both were 45 FPS. If I quickly raised the nose 45 degrees so that frame rate started to rise then leveled off (after a second or so into the run)both frame rates went up to 90ish but then in level flight may be 200 ft gained Beta settled at 60 FPS while the stable settled back at 45 FPS.
