I have same issue here.
My graphic card is NVIDIA GeForce GTX 760M. Driver software is up to date in win8.1.
I bought this laptop in 2014. It shouldn’t be “too old”.

Anyone know how to fix it with GPU Tessellation feature on?

Best regards,
Shaun

Are the drivers for both the Intel HD 4600 and GeForce 760M updated?
When you updated the GF drivers, did you choose the advanced - Clean install option?

Hello John,

I’ve solved my issue. My windows system couldn’t detect the newest driver, once I install newest driver manually, everything back to normal.

Thanks for your help.
Shaun
