I have tried 3 different F1 mods, RSS F1 2020, FSR 2019, and a 2017 mod, and I can not get DRS to work. If I watch AI cars, I see the flap open, but when I am driving, no luck. I have tried several different button mappings, and nothing seems to work. Any ideas on what might be wrong?
Check your brake isn't dragging slightly. Add some deadzone at the top to make sure, and see if that helps. You are assigning rear flap, right?
Thanks, I fixed it by pushing the brake just a tiny bit and setting it to MIN, all is well now, I guess the brake was on just a tiny bit before, so it would not activate.
