We have received reports that some people can't use MV after the 1.0.1 update. We have the older version to help our users.
To access the old version:
1. Right Click RPG Maker MV in Steam
2. Press Properties
3. Press the Updates Tab.
4. Select the Beta to v1.0.0
5. Let MV update.
While we're still looking for the cause of lag issues, we have pinpointed it out for the most part thanks to KisaiTenshi. Check if your graphics card has the following to minimize the lag:
Minimum:
DirectX 9/OpenGL 4.1 capable GPU
Recommended:
OpenGL ES 2.0 hardware driver support required for WebGL acceleration.
(AMD Catalyst 10.9, nVidia 358.50), iOS 8.0, Android 4.4.4*
Thank you everyone for your patience.
