We all know that racing fellow humans is more fun, but sometimes there aren't any around when you feel like racing. Which is why sims come with an AI. The R3E AI has a rather bad reputation, which in my opinion is ill-deserved. It works just fine, assuming you treat it right. First off, forget about the percentage settings. Nobody is equally adept at all car/track combinations, so you can't use one setting for all of them. You could in theory write down the settings for each combo, but....... So use the adaptive AI. As you may have surmised, the adaptive AI adapts to your skill-level. But it needs a baseline in order to work properly. Here's what you do: Step 1: Start a race with the desired combo, and run qualifying. The AI skill varies with the combos, and we need to find out whether you're faster or slower than the AI baseline. Step 2: Quit out, and start a series of 10 minute races without qualifying. If you were faster than the AI, start at the front. If you were slower than the AI, start at the back. The idea here is to be able to run consistent laps without interference from the AI. EDIT: Scratch the above. I'll rewrite it once I figure out the best way to train it. How many races you need to run in Step 2 is actually up to you. The more consistent your lap-times are, the faster the AI will find your pace, and adapt to it. For me it usually takes 2-3 races, and then I can get a good fight out of the AI. Couple of things to note. It's still an AI, and it's not perfect. Like most other AIs (and most sim-racers btw) it doesn't do particularly well in a crowd, so you need to be a little careful on the first lap.The further back you start the worse it is. The adaptive AI constantly adapts. Which is good, because as you gain experience and improve your lap-times the AI will follow suit. But if you've been down at the local for a few pints and a bit of a sing, and then run a race with adaptive AI, not only will you not be able to catch it, the next sober race will be ridiculously easy because it has adapted to your now slower lap-times. But to show-case what it can do, here's a short 10 minute race for illustration purposes. I've done 3 races before this one to get the AI to adapt to my pace, and put myself in 6th position. Look out for: 1. The AI is not robotic, it makes mistakes. Observe the blue/red car in 4th position, and watch it fishtail as he locks the brakes. 2. The AI doesn't give up after being passed. Near the end I screw up, the AI takes advantage and I lose P2. 3. The only time there is contact (when I move to P2) it is my own fault. Not once do I get dive-bombed or rammed in to. So if you're willing to do a little 'homework' to get the AI to adapt, R3E can certainly provide single-player entertainment. EDIT: Fine-tuned the OBS settings. Much improved video-quality. Driving still sucks though.
