I achieved 61.4FPS in Unigine Heaven 4.0 (extreme) on an external screen.įallout 4 Ultra: 60 FPS smooth, rare dips into 50s On the external screen, results are roughly as expected, with only a slight performance loss. I would not recommend this setup for internal screen use. Furthermore, some (even undemanding) games are rendered unplayable due to the stuttering the lack of bandwidth causes. Overall, there is a roughly 60% performance loss on the internal screen compared to normal GTX 1060 performance. Team Fortress 2 Max: 45 FPS, microstutteringĭawn of War II Retribution Benchmark on Ultra: 40 FPS average Just Cause 2 (regardless of settings): around 25 FPS No Man's Sky Ultra: Consistently well over 60 FPS, smooth Witcher 3 High: 29 FPS, often dipping to low 20s Game performance is very clearly limited by PCIe bandwidth as well (GPU usage often below 50%), but the framerates are interestingly tending to VSync framerates, such as 30 or 45 FPS.įallout 4 Ultra: 29.9 FPS, often dipping as low as 23 FPSįallout 4 Medium: 29.9 FPS, rarely dipping lowerĭoom Ultra (Vulkan): Constant stuttering (couldn't measure FPS as RivaTuner overlay didn't work) In 3DMark 11 the system achieved P93xx points, and 34FPS in Unigine Heaven 4.0 (extreme) on the internal screen. I have performed some tests on the internal screen, but results are quite underwhelming unfortunately.

Throughout my testing GEN2 speeds were maintained by the PE4C without issue, no freezes, driver crashed, BSODs. This way, the 660m is completely disabled and the 1060 can output to the internal screen.

I wanted to test internal screen performance using the 1060, so I proceeded to use Setup 1.3. The in-built 660m is not disabled this way though, and it was the GPU used for Optimus/internal screen output. There is no need to use any of the delay switches on the PE4C either, it is simple plug and play. Reboot, install desktop nvidia driver, rebootĪt this point the 1060 was properly recognised by the system (no errors at all), without the need to use Setup 1.3. Install PE4C connector into the slot (with the GTX 1060 and PSU already set up with the PE4C) Take out wifi card to free up mPCIe slot Uninstall mobile nvidia drivers, reboot
