Dear Piboso,
I haven't had a look at a version of GPB for quite some time, but out of curiosity I installed beta18b. There's a lot of things I like but also a few things that are really frustrating.
Pros:
+ nice new addition of Assen (could use a bit more detail though, especially grandstands)
+ nice Moto2 bike (engine sound could be better though)
+ sightly improved tire simulation
+ nice rider animations and hangoff styles
Cons:
- even on moderate downshifts (nowhere near high revs on downshifts), the rear locks up; the rear even locks up under braking when there is NO downshifting at all. this is not realistic at all - is this a broken slipper clutch simulation?
- the tires heat up very strangely and become almost unrideable after 2 laps; only way around that is to brake and downshift ultra conservatively and try to keep revs on downshifts under 40% of max rev which is absolutely unrealistic
watch this video for example on how aggressively real downshifts are made without rear locking up
- tire temps and grip simulation is too crude and artificial: tire grip out of the pits is best, after a few laps on track tires tend to slide very much; so in GPB with cold tires the bike has perfect grip and with warmer tires the bike has less grip and tends to slide out rather randomly - very strange; in reality it is the other way aroud
--> I know this is supposed to simulate overheating of tires, but it is broken; first there is too much grip with cold tires and the way the tires overheat is exaggerated in GPB; in reality overheating tires do generate less grip than optimal tire temperatures, but still more grip than cold tires. overheating tires do generate a bit less grip and the tires do spin a tad bit more (so accelerating is a bit slower) and the tires slide a bit more under ultra-heavy braking (so one has to brake a bit earlier), but they just do not magically slide or spin out like in GPB; in GPB when tires overheat a bit, the bike even tends to slide out with almost no lean angle; also in GPB you can brake latest when shifting down ultra conservatively (ultra late) whereas in reality you can brake latest when shifting down aggressively and using the engine brake power of high revs.
- in GPB the grip simulation has a tendency to be only on the extremes: either there is absolute perfect grip or no grip at all and the bike sliding like crazy
Overall I still like GPB a lot: I like the suspension simulation, the overall feeling of the brakes in GPB. That is what still creates the "itch" I felt when I discovered GPB more than 10years ago when I did lap after lap after lap trying to master the bike. But at the moment that joy goes away rather quickly because the tire simulation seems to be rather crude in terms of tire temps and grip simulation. Also the way the rear locks up under even moderate braking and downshifting is absolutely a turn-off and makes riding long stints with realistic braking impossible. At the moment I "enjoy" getting out of pits and using the grip of the cold (!) tires for one lap, after that it becomes a sliding festival or trying to "walk on eggs" with ultra conservative braking and downshifting and trying to have the tires in "non-icy icy sliding mode"... which is annoying and I quit after 15mins.
@Piboso: If you find the time, I really would like to hear how you explain the differences in what your sim does and what happens in reality on braking and downshifting (as shown in the video I posted above). Is there possibly a problem with the slipper clutch simulation? And where and how are you trying to improve GPB in terms of tire simulation?
Kind regards
