Kunos Simulazioni respond to recent CPU Occupancy > 99% issue with new advice for PC owners.

Following the popular update to build 1.12 of Assetto Corsa on Windows PC, Kunos Simulazioni have quickly realised a small proportion of users are suffering from a return of the CPU Occupancy > 99% issue that plagued many players during early builds of the game.

The return of the issue, attributed to amendments to the controls.ini file received in the latest build, has been acknowledged by the developers and advice has been issued on how to resolve this problem for the vast majority of players. With the update to the controls.ini file Kunos have brought to the game a more detailed FFB feeling for a number of wheel users, unfortunately this has caused problems for some players, especially those with older or home made wheel solutions. With the below advice issued today by Kunos the Italian team are confident any remaining CPU Occupancy issues will be resolved.

It is advisable to contact the official Assetto Corsa PC support forum if you still experience this issue after following the below steps.

FOR PC/WINDOWS USERS
With the new v1.12 update, we have introduced a new section in the "controls.ini" file located in your "Windows Documents\Assetto Corsa\cfg" path called "[FF_SKIP_STEPS]", that manages the force feedback update rate. The default value is now "0" instead of "1" and it overrides the old value located in the "assetto_corsa.ini" file (in the Steam game folder). This brings a more detailed force feedback and a better driving feeling. If you experience "CPU OCCUPANCY > 99%" warnings, please tick "Half FFB Update Rate" in the the UI Options -> Controls -> Advanced and this will bring the value back to "1". Not all the steering wheels can manage the maximum update rate, so no worries.

If you are using a very old steering wheel like the Microsoft Sidewinder or Saitek R440, or other hand-made ones, you need to open the "controls.ini" file, and set the "FF_SKIPS_STEPS" value to "4". It should look like this:

[FF_SKIP_STEPS]

VALUE=4

This should solve any "CPU OCCUPANCY > 99%" warnings related to the force feedback refresh rate.

Please always double check this value if you load controls profiles created before v1.12 update! In case, please create a new controls profile with the proper value!
