I suggest to check that when you play some affected game tha= t it actually runs at the 8GT/s x 4. One more thing comes to mind but you probably checked it already. The game = may not be using the eGPU and instead it is running on the internal one. With t= he Unigine benchmark it clearly used the eGPU. --=20 You may reply to this email to add a comment.
