Sim Racing

I know a big difference between ACC and iRacing is braking. In ACC, it's quicker to always go full brake abusing abs and much quicker lifting of the brake during tail braking. I think this is also a similar difference between AC and iRacing as well. For example in a gt3 car in iracing you may threshold brake up to 80% and slowly bleed off the brakes where as in ACC or AC you are gonna go full 100% brakes and have a much quicker bleed off of the brake. If you are noticing way more lockups when you hop back into iRacing, I'd put money on this being the reason. Go in with this understanding, and it will be like hopping into different cars. I forget which f1 driver said it but it takes about a year to go from being competitive in open wheel to learning what's gonna make you competitive in a heavy gt car, so don't beat yourself up if it takes time to transition between the sims as well. Hope that wasn't too much info and was helpful.
