Well I ran GfxBench 4.0 but there is not much to do wrong. Could it be that my dGPU has some sort of hardware issue? I would exchange the machine if it is a dGPU problem. I do like the SB except for this one issue.

The only reason I was benchmarking the dGPU with Cinebench & GfxBench was that it was only giving 4-5 FPS for an OpenGL game "Zwift" I was using. While the built in 520 was giving 18FPS. I would at least expect it to outperform the onboard 520. If it did not way spend the extra dough...

As further proof that the additional Nvidia GPU is weak. I ran Cinebench 11.5 OpenGL test both with and without the dGPU dGPU = 26.32 FPS iGPU 520 = 28 FPS Why would MS put a GPU that performs worse than the integrated GPU?

I have found that the dGPU is much slower than the integrated 520 in the one OpenGL game I use. I have to disable the dGPU to get acceptable performance. 4-5 FPS with the dGPU and 18FPS with the 520. So perhaps you are seeing the same thing and the dGPU either has terrible firmware or the...

My dGPU is crap even compared to the onboard 520. I only had one gaming requirement it had to run one OpenGL game (Zwift) at least equal my 2year old laptop without a dGPU. As it stands the SB i7 w/dGPU can only muster an unplayable 4-5 FPS. The integrated 520 runs at 18FPS and my old laptop...

I downloaded GfxBench and ran the tests. In the offscreen tests it seems to test as normal. The onscreen tests are way below what they should be. Given that my OpenGL game does run like crap with the dGPU it seems to indicate something is wrong. Do I have a bum GPU? Can someone look at the...

Well it very well may be zwifts problem but it is not just selecting the wrong GPU. If I detach the base and run, it gives acceptable performance. If I run with the base and ensure it is using the dGPU it runs at a third of the speed. With GFXBench the Tesselation score is much slower with...

More information. If I select the onboard GPU when I launch the application it still seems to want to use the discrete GPU. It tells me I cannot detach the base even if I select the onboard GPU. I have to start the program with the base detached so it doesn't try and use the dGPU. Then I...

I had BB check there SKU's and they only had one. You may be right that they changed the design recently. You are correct though the box doesn't state SB. I guess I will return this and look for a newer version.

So I went to Best Buy tonight and tested the mDP and apparently it is designed for a SP3&4 and not the SB. By that, I mean that the rubber surround is angled for the angled body of the SP. It fits in completely due to the matching angle. The SB has a flat side and the rubber surround pushes...

one thing that leads me to believe the GPU is working is that I ran passtest testing tools and it claimed that my GPU was double the speed of my old laptop. Presumably if it was not working it would not test at double the speed. So perhaps it is a firmware driver or something off in the...

I purchased a microsoft display port/HDMI plug for my surface book. I am finding the plug does not 'stick' properly. I insert it and it slips back out. Should I expect it to click in and stay or is this an issue with the cable or just a poor design? I have to keep on pushing it in or it will...

So one important requirement for me was that my SB be able to run Zwift (zwift.com). This is a graphics program for cyclists. Anyway I didn't expect my SB to be a graphics powerhouse but running this program with the GPU only gives 4 to 5 FPS no matter what the resolution is low or high...
