When I run the latest version of Houdini (12.5.393) on my laptop it says it's running in Software opengl mode and it's therefore dog slow.
My graphics card is an Nvidia Geforce GT 640M, I've never had any trouble running Houdini with this type of card before, any settings I can tweak to make it work, driver is up to date version 314.22

Also, Houdini version Houdini 12.5.316.22 does not show the same warning, so has something changed very recently?

Just found this

will try the older driver

If it's Windows, try setting the environment variable HOUDINI_OGL_SOFTWARE to 0.

We made a change for AMD's version of Optimus (I forget the marketing term for it). Try running the App here:

and post the results. That way we can fine-tune the heuristic that detects Intel graphics. Thanks!

Setting HOUDINI_OGL_SOFTWARE to 0 makes the warning go away but doesn't seem to fix the problem. My viewport render is messed up.
See attached.
Will try the older driver, but it worked fine with this build Houdini FX 12.5.316.22

Older driver 306.97 has other redraw issues…. trying 320.18 which is the latest one.

Same redraw issues with that one. Geometry not displaying properly. Looks like I'll have to roll everything back to what I first had. 314.22 with Houdini FX 12.5.316.22

What is the SOP information for the geometry (opinfo /obj/warriorII/file1)? Also, in Help > About Houdini, Show Details, is it indicating that the OpenGL renderer is the 640M?

When I go to help > About houdini it just crashes. Even without the file loaded.

Sop info attached.
