After installing and playing the game for the first time, the shader cache is created. Any stuttering should be resolved once the cache has been created.

You can force the shader cache to be created by going to in-game menu > SYSTEM > Graphics > Compile Shader > ON, and returning to the title screen. Please note that this may take between 35 to 90 minutes depending on your PC system specs.

Please ensure that the shader cache is enabled on your GPU settings to allow the cache file to be generated correctly.
