Today we are testing 8 games as part of our investigation. We first tested with the eGPU connected only to the laptop, using the integrated display. However, we also tested using an external monitor as this can affect overall performance of an eGPU. All test we done at 1080p, 1440p and 4K when using the external monitor, but we are limited to only 1080p testing as a result of the Blade 15's panel resolution.
