Intel Iris Plus 640 GPU OpenGL issues

I have a Dell XPS 13 and it too has the "Intel Iris Plus 640".

It is unusable when drawing some outlines. (I understand this is an OpenGL problem).  I'm also looking for a solution.

I have done the "Realview Hack" to my system. When I did it, I had to try several different values before I found one that actually worked. Also note the hack does not work with every card........

My only suggestion would be more google research and see if others suggest a different value by chance.

Realview with Intel IRIS plus 640

After putting together bits and pieces of information, then troubleshooting problems after upgrading to Win10 Pro and then having it not work after updating to the latest video driver.  I think I figured out what's important to make Realview work with Intel Iris Plus 640.  Mine being on a Dell XPS 13 9360.

First Thing:

Running Regedit, go to Computer\HKEY_CURRENT_USER\Software\SolidWorks\SOLIDWORKS 2018 (or what ever year you're on)\Performance\Graphics\Hardware\.

Go to "Current", then double click "Renderer" and copy the name of your GPU as SolidWorks sees it.

Expand the "Intel" folder and you see several Intel cards but not ours.  We need to have a key with the exact name we copied from the "current" folder.  That key needs two sub-keys,V001 & V002, exactly like the other similar cards in the Intel folder.

There are two things you can do.

Create the new key and sub-keys complete with names and Dword values exactly the same as say, the Intel(R) HD Graphics P keys.

Or, since we don't have the Intel(R) HD Graphics P card, just rename it to be our Iris Plus card.

The values for all the cards in the Intel folder are the same except for the first one so don't use it.

Second Thing:

Now expand the "Gl2shaders" folder then the "Other" folder.  Here you will find other Intel cards but not ours.  Add a new key and name it exactly the same as the "renderer" in the "current folder".

Add to it a Dword (32 bit) called "Workarounds", and give it a value.  At this point, it seems any value will work.  I can even leave it set to 0.

Third Thing:

Pay attention to the first thing.  When I updated my video driver to the latest, Realview stopped working. WTF?  I searched the registry for every instance of "Intel(R) Iris(TM) Plus Graphics 640" and saw it didn't find the one in the "Current" folder.  The new driver now calls it "Intel(R) Iris(R) Plus Graphics 640".

Notice the "Iris(TM)" is now "Iris(R)"?  I renamed my keys and I was happy happy happy!

Got Realview on my laptop,  The graphics act the same as my workstation, integrated preview and all, and it has a Quadro 600.

Hope this works for everyone with this GPU.

I was able to use this fix but now my SolidWorks is instantly crashing.  Any suggestions?

2019, happy new year!

This is just a status report on how I’m doing with RealView.

On my Dell XPS 13 9360 I updated the BIOS and all drivers from Dell, graphics included.  Windows 10 is up to date.  SW 2019 sp0 is installed.

Using the procedure above, I have RealView working with 2019.  However, SW crashes when making a sketch.  When I reinstall the most previous driver from Dell, which is “Intel-HD-620-and-Iris-Graphics-640_M10YG_WIN_22.20.16.4836_A09”, RealView works very well.  Drivers from Intel don’t work on the Dell.

I also tried running the recent Real Hack 6.0.0. It made no difference in this setup, though it works very well with regular cards in a desktop and is easy to use. It works with 2018 & 19 and may work with earlier versions.  It may work on other laptops as well.

Summary:

2019 RealView works with my Iris Plus 640.

Driver 22.20.16.4836_A09 is good.

Driver 23.20.16.4973_A10 is bad.
