Before entering the game, there are some points to raise. First, the Blackmagic eGPU will not work in Windows 10 using Plug and Play Bootcamp.
There are ways to do it, but they are complicated, and we do not recommend them to everye, but to those who are technically the most knowledgeable. The Apple eGPU implementati really requires that it be used with an external mitor, such as LG’s UltraFine 5K display, but there are individual terminal commands to allow the LG to run. EGPU to perform calculatis without display.
If you need to use multiple applicatis at the same time, there is actually a script called set-eGPU that will allow you to use Blackmagic eGPU without an external mitor many applicatis that would not normally support it under High Sierra.
We will see how to cfigure and test the performance of a rebooted eGPU the internal screen of the MacBook Pro in a future article.
We have also cfirmed that you can use a USB-C to DisplayPort cable or an HDMI cable to cnect just about any external mitor, with a limitati of 4K to 60 frames per secd.
Switching the mitors
Ctinuing the test, we switched to a 4K mitor and plugged it into using a USB-C to DisplayPort cable. In this case, we used a Samsung LU28E590DS / CR 4K mitor, which has much better performance and color saturati than the LG 5K.
Under these cditis, we are still watching an average of 30 frames per secd in 4K Epic quality, but that seems hestly so much worse than before.
We lowered the graphics quality to a high level, which translates to an average of 40 and occasial peaks at 50 frames per secd. It’s still playable, but we still do not reach nearly 60 frames per secd.
With Blackmagic eGPU
Then we plugged the Blackmagic eGPU and the LG UltraFine 5K screen, to see if we can play Fortnite at a 5K resoluti.
In this case, the resoluti was set to 5120×2880 with the graphical settings at the top, including the shadows. As so as you enter the lobby, you can immediately see how good the graphics are, with everything that appears clearly.
At 5K with the default settings, frames per secd are in the range of 30 to 32, which is actually not too serious if we csider that it is played at a resoluti of 5K.
That’s quite a feat, csidering 5K at 14,745,600 pixels has almost twice the number of pixels in 4K with 8,294,400.
Even though the frames per secd are close to what we saw with the MacBook Pro by itself, it’s actually a lot more csistent and the gameplay is much more fluid. You do not see any frame falls out before with the MacBook Pro ale, which makes the game totally unplayable.
Even at this graphic setting, the 5K resoluti still means everything looks pretty detailed. At this point, the game is sitting at around 40 frames per secd, but the game is still smooth.
Going down to 4K, 3840×2160 and changing the graphical settings of the “Epic” to the maximum, the game starts strangely to appear a little blurry, as the game turns slightly below the optimal resoluti for the mitor.
With these settings, the average game is about 35 frames per secd, which is not too big, but it is very smooth. Playing 5K with average quality graphics seemed a lot better than that.
The best thing about this eGPU is that you can plug it into LG’s UltraFine 4K or 5K mitors using Thunderbolt 3, which you could not do before with any other eGPU. Otherwise, if you have another screen, the Blackmagic eGPU will always work with HDMI or a USB-C cable to DisplayPort.
