Not at home but if I remember correctly Broken cumulus clouds at 9000 ft in afternoon
At 500ft I put heating control on manual, temp control knob to 2 o'clock, foot heater lever to defog
30secs later popped up to 8500 ft, started steep dive on sams and activated emergency vent but still could not see target. Was in vr mode so had to lean my head out the cockpit to see the target. Far less realistic than no fogging in the cockpit. Couldn't see any detail through the hud.
Do the same thing in the mirage F1 and can see the target clearly (no fiddling with heating and venting etc )
I don't mind fiddling if it gets a result but is no fun and frankly frustrating and unplqayable if you just can't see the target.
Would rather see detail with the same clarity as the in the other planes and forego the fogging realism.
