Even with a dual core LFS only utilises one core so you can't directly compare the two. Limiting frame rate helps with cpu utilisation so that it's not pumping out data to the graphics card all the time and can do more physics calculations.
As I understand it, the physics are calcualted per car since they're all doing something different. In patch V the car infront on the start grid is calculated in hi res which would use even more cpu. I don't think you can change physics calculations otherwise the game would play different, I'm only basing this off my own experience and what I've read on the forum.
Hmm the little work I've done in vray suggest increasing subdivisions to get rid of noise, thogh render times incrase 4x when doubling the subdivs, but the renders look much much better. 8 hours is already a long time hehe
Those options only in SHIFT+U mode. Hold CTRL+ left and right arrow keys for camera roll. V or TAB changes height and also CTRL + up and down arrow keys.
There's a lot of physics to calculate for 20 cars and it's all done by the CPU so that's the limiting factor. The only thing that would stress the GPU is AA, AF and high res.
Oh yeh I forgot.
I get about 40fps with a full grid, not that it happens often
Damn camera was too faraway and everyhting was too bright to see anything. Zoom into the screen more or adjust the room lights next time for a vid I really couldn't see much
Seriously guys, search. There's been heaps of threads about starting rendering, just read some of them, if you're not even going to bother spending little time reading a few threads I doubt you're willing to soend the time to elarn tutorials etc for rendering.
Yes I make my own setups adjust them to my liking and I adjust them to wind speed because the league I'm in atm uses high wind speeds and to me it makes a difference and I like to get everything I can out of the car.
