Performance aside, the non-CSP versions also typically allow the AI to drive in a more respectable manner when compared to the more advanced physics modeling and scripting we have onboard the CSP versions.
Sorry to interfere but you have triggered me with this one. Could you elaborate on this please ?
I'm interested as a solo player that has developped his own DumbAI app to simulate race strategies, much similar to your RARE app (as I only discovered recently unfortunately)
I frequently read here and there that the AI of native AC is really poor, that CSP extended physics make it slower, that new CSP AI modifications make it even worst etc...
I made some tests myself and had this results:
Conditions were Monza Kunos , CSP 0.3.0p338, 5 laps, quick race, 11 opponents, AI 100%, agression 0%, no fuel rate, no tyre wear, no damages, best tyre compound set by DumbAI, ideal conditions for track and weather
Lotus Exos Stage 1
no extended physics attempt 1 : best best lap = 1'29'0 , worst best lap 1'29'9
no extended physics attempt 2 : best best lap = 1'29'0 , worst best lap 1'29'6
no extended physics attempt 3 : best best lap = 1'29'2 , worst best lap 1'29'9
extended physics, no new AI behavior attempt 1 : best best lap = 1'29'2 , worst best lap 1'30'5
extended physics, no new AI behavior attempt 2 : best best lap = 1'29'2 , worst best lap 1'30'5
extended physics, new AI behavior attempt 1 : best best lap = 1'29'3 , worst best lap 1'30'6
Lamborghini Countach
no extended physics attempt 1 : best best lap = 2'14'9 , worst best lap 2'15'7
extended physics, no new AI behavior attempt 1 : best best lap = 2'15'7 , worst best lap 2'17'1
extended physics, new AI behavior attempt 1 : best best lap = 2'15'5 , worst best lap 2'17'6
Tests are a bit long to perform, I'll continue them myself as time allows, but I'd be really interested by any information on this particular topic . I read it depends on tracks , car, mods or Kunos etc.. but it would be nice to have informations directely from someone very skilled on physics modding, if you can share some !
