Hello,
if you drive with a car on the Ramp @ Tisy Base or a traintrack, the fps go instant from very bad to normal as soon as the car is on the ramp or traintrack.
When driving back from ramp/traintrack to normal ground fps go instantly bad again.
Also works while jumping with a car.
Maybe this helps for fixing issues with bad car fps right now on stable 0.60.
Drive on Tisy base ramp building, a traintrack or jump with car
Tested with sedan on tisy base ramp, tested with 4x4 Lada on several jumps and traintrack
Additional info: When jumping with a car the fps will go for that time to normal too.
Tested with 4x4 Lada several times. Somehow elevation above ground will normalize bad fps while driving
My assumption is that all this is just related to collision detection.
*this is just my guess to explain what you experienced*
btw, when you say "bad fps", can you give a figure ? and what is your idle framerate while not driving ?
When i start driving with f.e. 70fps it decreases over time. After 10 or 15mins it goes down to 10-12 fps.
Idle fps is 70-120 depending on location.
Alright, so when you drive on the tisy ramp your framerate goes instantly from 10-12fps back to 70fps ?
Yesss ! Already see that when jump with a sedan (volga) Normal FPS comes back ! I have found a full car with all doors, hood, trunk are pristine !!!! But it disappears because of the non-persistence system bug with Bohemia !
