So far I know DRS only can be activated when: * Within 1 second of the car in front of you when passing the detection zone * Inside the DRS zone * After lap 2 As far as I can tell, when you do test rides, so without competitors, DRS seems enabled every time you are inside the DRS zone. However, I notice sometimes I see the DRS available (flag in HUD and blue led on Ultimate gen2 steering wheel), but pushing the mapped DRS button doesn't activate it (no active flag in hud or 2 green leds on the wheel). Sometimes it works, sometimes it doesn't. Am I missing some prerequisites for the DRS to be activated? Certain speed, certain rpm, something else I'm missing? The buttons seems to work always, when testing it in Windows device manager, so I doubt it's a hardware issue.
Full throttle and no brakes. Worth checking aswell if the brake pedal is flickering a tiny bit or similar.
Check the brake pedal, foot completely off and large deadzone. Probably full throttle that is the issue. I'll check when I'm back behind the computer.
