Low FPS after pressing Esc, on menu, etc.
Total que a los que teneis una cafetera por PC o apenas os tire de FPS bajar los efectos simultaneos de audio o quitar el spotter plugin y en el caso de seguir con los problemas poner el antianalising a 1 (esto se hace desde fuera del rfactor en el acceso directo de "rFactor Config", donde esta lo del DirectX)Some people have very low FPS if they press Esc to go back to the menu, or when they're going to drive.
This error, named "2 FPS bug" on RSC forums is related to the presence of spotter plugin.
To fix it just remove the spotter plugin and it should work. Or go to "Basic Settings" of spotter plugin, then "Audio" and lower number of effects (Try using 10).
(Thanks to Bosanac1 for the solution, and TonyP for the lowering number of sounds tip)
Other users say it's due Anti-Aliasing (FSAA). Try to set it to Level 1 using rF configurator if the problem persist.
