Just got iRacing this morning and have been trying out the Street Stock and the Mazda all day. I did try 1 race with the Street Stock which didn't go so well but I'm more interested in the road side anyway. I did a few practice sessions and got my time down to a 1:05:6XX at Lime Rock Park. The problem is I can't seem to string together 2 laps in a row without crashing. MaybeI'm just too used to more 'arcade' games like F1 2012 ? I'm really enjoying it nevertheless.
Smooth, smooth and smooth ! The three most important things
Second most important, at least for me, is the Field of View (FOV), in sim, under the graphics options, there's a FOV calculator, get a tape measure, and set it as it tells you. If you are on a single monitor, you may feel you can't see any thing, but you'll have a much better view of the apexes.
When you can string together 5 laps, try a TT, or a ghost race. On the homepage, under events in the top menu, there is "Watch/Ghost/Crew/Spot" which allows you to spectate on a race, wait until the Mazda Cup race starts, the pick a race to Ghost, when the sim starts you can actually drive in the race, but no-one else can see you and you can't hit any one. It's a great way to practice racing without any risk.
Bear in mind that iRacing weeks, run Tuesday-Monday, so the track will change at midnight tonight. The Mazda Cup will be racing at Summit Point tomorrow.....
Remember, have fun
