[FIXED] This problem was fixed by a Nvidia driver update. If you update your Geforce driver to Geforce Game Ready Driver 384.76 whql you should no longer have this problem.

There is a major problem relating to 3ds Max 2017/2018 in terms of viewport freezes. When this happens, you can still interact with the modifier stack, menus, etc... but the viewport will not respond to anything. Sometimes Max will actually crash, but often it will not crash. It usually does not lead to a CER (Customer Error Report form), which means data for this problem is not automatically being sent to Autodesk to analyze.

This is not a Wall Worm issue. This is a problem with the NVidia drivers. It appears to be related to the Nitrous viewport using DX11. Unfortunately, switching to DX9 viewport will make some functions in WW no longer work--for example, the Black Mesa shader for WorldVertexTransition and the Lightmapped_4Wayblend shaders both require DX11. However, there are also other reports that DX9 can crash 2017+ too.

This problem may be limited to systems with Geforce video cards on Windows 10.

If you experience this bug, please submit a Bug Report to Autodesk to help escalate a resolution.

You can include reference to this article in your bug report as well as a link to these threads:

• 3ds Max 2017 Viewport freezing and stopped working
• 3ds Max 2017 directx shader crash
• Viewport Freezing
• 3ds Max 2018 freezing viewport bug (same as 2017)

Hopefully Autodesk will find a solution for this soon.

Please also post any information you have on this in the WW Forums.
