I know that there have been many posts on this topic, including Nuno Espan someone (sorry, no offence) super fast Gp4. I have searched for this topic on this and other forums, but non of the points mentioned work.
I have found my optimum in the game menus, and have set the cars in the mirrors to be seen to only 50m, but that is all I can do. I got fed up with 17FPS so have set it to 21FPS. I don't bother with the PO reading any more because I've heard it sends the PO up pressing it (although i didn't have any probems with sky messages, so I don't know if this happens with me).
In the dry, lap one of Spa for example takes 4secs more than it does in game, Austria and Brazil (the two tracks with the highest PO for me) take the same.
It is a bit slow sometimes though, and I would like to get it faster, so I can play in the wet. I'd like to get about 20% PO less (even though the reading might be wrong, it's wrong by the same amount every time!) so it's back to where it was at 17FPS.
Has anybody got any tweaks in the f1grpahics config that could do this please? I have car and track geometry on low, so there's nothing that can be gained by lowering cull points, and I have the mirrors set to cars only at 50m.
Thanks for any help.
