VR_Stick did a test of three settings of Terrain.ini. The setting is above each picture. All comparisons are using SweetFX however I have included a non-SweetFX of the Original Terrain.ini as a control. All are in Balanced Preset except the last to show the difference to the Ultra setting. Resolution is 1920x1200.

I have not done extensive testing of the 3rd setting, however in Balanced preset in QMB I seemed to have little to no hesitations where previously there were some. Keeping my fingers crossed for mp.

This no longer applies as you can change these settings in-game now.
