Still makes no sense. The reason it's such a problem to develop is because we need to do an approximation if the simulation needs to run in realtime on old hardware. The more power we have available, the less simplified the approximation needs to be, and the more accurate it will be at the same time.
To me, it seems that if you want cutting-edge physics, you should abandon old hardware. I'm not saying up the minimum requirements to the best quad core processors etc.
I believe the calculations are quite memory and CPU intensive and would benefit majorly from parallelisation, so a processor with 2 cores or just 1 core with HT could help majorly if the code was optimized for it (multithreaded).
Have you even checked how little it takes to run LFS currently? It's possible to attain 30 fps with a 1.2 GHz Celeron, 512 mb slow RAM and an onboard video card with 32 mb memory. That was slow 10 years ago..
It's hard to see, but assuming the deformation is making the tyre deform in such a way that it's skinnier on the left, the tyre would be rotating clockwise.
And yes, I think 2 years is too long because it is. Not for creating the perfect sim, but that's a bad idea to try in realtime without making the minimum requirements some supercomputer. At least increase the minimum requirements to some processor post-2008, and perhaps even utilise nVidia cards with CUDA which is awesomely fast parallel processing.
I have never heard anything as unrealistic as expecting a world-class sim to run on ancient hardware. Quit trying.
This is more than many people hoped to get for their LFS Christmas, not too shabby at all.
Condensing all the calculations of a realistic tyre model into a realtime model is of course really hard, but what I don't get is why it takes such a long time. To me it seems that once you have a pretty good approximation of this model, you're not gonna get much further without increasing the requirements of the computers. For a long time I think the answer for the updated physics is to not support the very slow computers that you insist on. :twocents:
