Tried 1.4 live briefly last night - still getting stutter when in Metal Rich asteroid fields (example: Xihe 1 Ring A Hi-RES). This took the form of a freeze of up to approx. half a second every 7-15 seconds when flying through the ring, but also sometimes happened when opening one of the ship's panels (which was sometimes accompanied by the audio stuttering/crackling slightly, which I almost never had before).
Just tried other asteroid types in 1.4:
Icy - small hitches every so often, nowhere near as bad as Metal-Rich
Rocky - OK
Metallic - OK (but this was a belt cluster with very few asteroids)
I thought I would take the notes I previously made on when I get stutter and the frequency and do a then and now comparison:
- exiting from super cruise (stutters for a few seconds esp. when facing a station) - then 95% now OK (I think, need to play more)
- exiting from hyperspace - then 85% now OK
- during supercruise usually when target is 1-3 LS away - then 75% now OK (shader warming seems to fix this for me, AMD card)
- during hyperspace sequence - then 100% now 100%
- during interdictions - then 40% now: need to test
- major stuttering and slow-down in some RES now: see above
- during 'spinning ship' loading screen - then 100% now 100%
- rotating coriolis on main menu (minor hitch every 3-4 secs) - then 100% now 100%
