While that might work, it’s not really a solution
As far as I can tell, GPU tessellation should work fine for an Intel GPU running OpenGL 4.0 and later. Yours appears to be using OpenGL 4.3.0.

Unfortunately some of the Intel drivers suffer from this problem and I have been able to repeat it. I was by default disabling GPU tessellation on Intel drivers that only supported up to GL 4.0; looks like I may have to do so with the ones that only go up to 4.3. My Intel driver supports GL 4.4 and works great with the feature.
I tried the latest driver for my chipset with windows 7 support 184.108.40.20678 and the one before it 220.127.116.1114, both supporting OpenGL 4.3, same result with both, i have to disable tessellation.
In Rhino 5 there is no problem, graphic seems much faster.
It’s a bug in the Intel driver and unfortunately I don’t have any good contact information at Intel to tell them about this bug. Nvidia and AMD drivers appear to work with this feature. I do know that the newer Intel Iris drivers also work with GPU tessellation enabled, but that is probably a different GPU than what you have. If it weren’t for this driver bug, I wouldn’t even make a checkbox option on the OpenGL settings page and just always keep the feature enabled.
Sorry, but I don’t have high hopes of fixing GPU tessellation for your specific GPU.
