    While its not as light as its Gram 2020 brethren, this device looks like almost the same as the grams externally. It comes with a GTX 1650 GPU that can handle everything, except ray tracing.

    This device is actually an upgrade over the previous generation Gram series in terms of CPU performance. I just posted on the new Gram 2020 thread that its CPU performs WORSE than the previous generation. The CPU on this device does perform better than the previous generation: Where Gram 17" 2019 took 3.5 hours (three and a half hours) to build our software, with identical RAM/HDD/etc. the 17" non-Gram 2020 nVIDIA version built our software in 2.75 hours (two and three quarters of an hour).

    The only problem with this device is that it locks GPU FPS at 60. There is no override in the nVIDIA GPU settings panel. Does anybody know how to disable this lock? It seems frame locking is a new feature introduced by nVIDIA, but if its not exposed in the custom UI of the OEM's GPU panel, are we stuck with this limit? Makes doing an apples to apples benchmark comparison difficult.

    (for example against the new Surface Book 3 which has a superior GPU)

    That's strange, it sounds like vsync is turned on in the nvidia control panel or something. Can you just install the drivers straight from nVidia. If you use the DCH drivers you should be able to grab the control panel from the MS store.

    I already have the control panel as was automatically installed by Microsoft Update and vsync is indeed forced off. There's no user visible setting for the frame lock though.

    Is it possible to install a stock nVIDIA driver on top of this configuration?

    No idea, I would imagine it is. Have you tried?
