Apparently gt5 with the latest patch is pretty good and much better than before.
I havent personally tried it but i will.
The problem i have with iracing is that i never quite feel im in control of the car they just seem to be made harder drive than they should. Maybe its my hardware not correctly configured or a setup im using is crap but i just feel like there is something missing.
I can jump in a car on lfs and straight away feel the car, can feel its limits and just get a general good feel factor. Same goes for gt5, nkpro, rf2 even gpl!
Dont get me wrong tho i dont hate iracing i think its decent enough but when you see stupid stuff going on with the physics like on some of the videos it just makes you think.
And why would they not create a flat physics engine which all cars use then change attributes to the cars, why have every car using seperate physics? Just seems a bit old school and possibility of so many issues.
Im sure gt5 just has 1 main physics component and they just change the cars attributes, weight, power, heights, widths etc and the physics engine just sorts the rest out.
