This message is caused by having 3ds Max bitmap paging feature enabled. Bitmap paging often drastically reduces rendering performance. It is always strongly suggested to disable it.
Possible causes:

Solutions:
- Open 3ds Max Asset Tracker (Shift+T)
- In the top menu, under Bitmap Performance and Memory, uncheck “Enable Bitmap Paging”
- Save your 3ds Max scene
- Close 3ds Max
- Start 3ds Max again
- Open your scene
- Open 3ds Max Asset Tracker and make sure “Enable Bitmap Paging” menu entry is still disabled
Note: Disabling 3ds Max Bitmap Paging requires complete 3ds Max restart to take effect!
