Game Stock Car Extreme V1.50 available now

Reiza Studios have released Stock Car Extreme V1.50 on Steam & via GSC Sync.

The V1.50 GSCE update will include the first in-house compiled executables, removing all the external code injection DLLs from the previous releases. Several features that were previously developed using injected code have now been rewritten into the codebase. Also, several new features, improvements, and bug fixes have been implemented in the same manner.

The update also brings you some new content in the form of the Mitsubishi Lancer Cup Series (Lancer R & RS models) and the Velo Cittá Circuit (2 layouts).

Check out the full release notes below.

Because of this major change, Reiza Studios urge you to carefully read the important release notes to ensure you do not encounter problems after updating.



  • Current users MUST create a fresh player profile (delete the old one from \USERDATA) otherwise the game won´t launch.
  • New users MUST note that GSC Config may not launch directly from Steam, which will result in a Crashdump – run it from game install folder:\SteamApps\common\Stock Car Extreme (will be fixed in a following update).
  • After creating a fresh profile, make sure to double-check your driving aids & controller speed sensitivity to make sure they match what you had before
  • If you get a crash on startup, make sure you have installed the DX9.0C that comes with the game (by running \Support\DirectX\Install\DXSETUP.exe).
  • If you do the above and still crashes, or if you get a black screen when escaping from a session, delete d3d9.dll from the game root folder.
  • If you get a blank screen after hitting escape from the track, delete d3d9.dll from the game root folder.
  • Since there are several new parameters for both cars and tracks, it is possible that some MODs will not work 100% and will need to be updated to use the new features (please consult this thread to learn you may update your mod).


For the new STEERING ROTATION feature:

All Logitech & Thrustmaster wheels with adjustable rotation should be working with this feature. Fanatec wheels should too, except for the V2 wheelbase which is still in development.
If you have any of the supported wheels, it is recommended you set Enable Custom Steer Rotation to NO from OPTIONS > CONTROLS, and let the game customize the appropriate rotation range for each car:

If Enable Custom Steer Rotation is set to NO, the rotation range below it has no effect so you may ignore it.

Some cars will also allow some range for adjusting rotation from the garage menu – ex. F-Extreme is defaulted to 360º, but you can increase that 450º from the garage. Others (like the Lancers) are fixed at 900º.

In case you do not have a controller with adjustable rotation, OR if your steering wheel is not yet supported by this feature, you should set Enable Custom Steer Rotation to YES, and define how much rotation range you have in your controller in the setting below – the game should then work same as before (with any adjustment per car done manually both here & controller profiler) and STEER ROTATION SETTING in GARAGE1 menu will have no actual effect.

Please note that in either case, using old controller presets is NOT recommended – we recommend you start one from scratch.

Further known issues with this version (to be addressed in the next release):

  • GSC Dedicated is unstable when running from Steam;
  • DRS activation & tire compound selection are not stored in replays;
  • No compound restriction per track in F-Extreme & F-Reiza;

These issues and the ones aforementioned will be fixed ASAP.
