[iRaN] iRacing April 8 Update

iRacing Update



While the new build update is scheduled for June, the iRacing development team decided to deploy an intermediate update fixing some ongoing issues.

The main part of the update addresses some frame-rate related improvements such as shadow volume performance, a dynamic level of detail function and cockpit mirror priority options. All these improvements should enable users to bump up their maximum frame-rate. Furthermore, the update also fixes a few small bugs and adds updated setups to a selection of cars.

Changelog:

Framerate Improvements

Improved shadow volume performance at night tracks, when driving near large
groups of cars, such as during starts and re-starts.
Dynamically reduce the level of detail of cars and pit related objects, when
driving near too many high detail objects, such as during starts and restarts.
Added some clamping to the level of detail for mirrors and cockpit camera to
prevent detail level from going too high when it shouldn’t.
If both the virtual mirror and cockpit mirrors are enabled at the same time, the rear-view cockpit mirror is now lowered in priority to be after the side mirrors. Now you can say you want 1 cockpit mirror and the virtual mirror, and you get the driver side cockpit mirror and the virtual mirror, instead of the rear view mirror and the virtual mirror.
