Bear with me... long:
I have been racing online with iRacing... this is my 2nd winter and while I'm not an alien I do pretty well considering I do not spend much time on it. This past week I was struggling to get up to race speeds in the new MX-5 cup car and hit a wall around a second off the pace of the middle (regular guy) tier. I confirmed my middle of the road status by starting 5th, 6th and 4th and only improving by 1 position each race. So... consistent and average.
I happened to be at a friends house this week - he is a new rookie and we were just screwing around to get him up to speed. I logged in as me, on his machine, and easily did over a FULL SECOND a lap better, consistently for two full practice sessions. I came home - and went right back to my normal lap times.
He has the same wheel and the same processor - can video card or memory performance help lap time? My frame rate is good - but he has a better card. We both have great ping times so its not a network thing... The conclusion seems plausible but the implication is completely unfair and something that the software should be able to compensate for to even the playing field.
Am I facing the same issue I have with my REAL car and find that even in the fake world... I can't afford to win?
