Thanks a ton for you help. Funnily enough I actually reinstalled the game yesterday hoping the same and alas, no dice. I'm hoping maybe I can find something in the LoL code to change that will force the GPU but that will most likely be a long shot. At least now I know I'm not the only one and it's not something I did wrong. Thanks again for your help and however I can add to your rep, I'm happy to!

Ok I reset the PRAM and re-ran the automate eGPU. Same results. Diablo runs like an absolute dream and LoL still running like booty. Even if i only run LoL on a single screen it still stays around the 33FPS and feels clunky. It doesn't matter if I run the settings maxed out with vertical sync etc or what. It always seems to hover around the 33FPS mark for some reason. It's like LoL is somehow auto-limiting the GPU use behind the scenes. There is a setting in game that allows you to change to uncapped, etc but it seems to have no effect on the performance at all. I'm at a complete loss for what is going on here. Btw I just tested and it definitely switches between GPUs when I move the window between my retina screen and my External Monitor. Bring the window to the retina screen, frame rate goes up immediately and laptop begins to get hot, fans turning on etc. Bring the window to the external screen and the laptop cools back down, frame rate drops, but the eGPU doesn't seem to work any harder at all and clearly isn't being used to potential.

Additional note: I installed and ran Diablo 3 and after playing that... the graphics performance on League increased a pretty good bit. Still not even running the GPU hot at all though even on all high settings. There is definitely still some untapped power here but for some reason playing Diablo made some configuration setting change for the better, but not best. Any other ideas as to what setting I could change or script guys?

Yes I got the 33FPS on the external with the eGPU. I achieved 60 FPS via the internal GPU both on the external and on the internal. 1) If I select the default OS X drivers in the Nvidia control panel, the Mac doesn't boot. 2) Ran the Unigene test and on the retina screen using the internal GPU I got between 8-11 FPS on High. On the external with the eGPU I got 70-80 with both side monitors plugged in so it definitely worked there no problem. It also run Ultimate similarly with no problem at all. So it seems to do great on the test, but when I run the game, it only gets about 33-35 and this is just League of Legends we're talking about here so nothing crazy. Is it possible its the game that is not playing nice? I've tried using GFX Card Status to force using the eGPU but it doesn't recognize that I have two GPU's. Automatic switching is also not an option in the energy saver preferences. Is there a way to control what applications use the eGPU? Running VMWare for my Windows apps runs flawlessly on this setup btw. I'm absolutely in love with it but for some reason, League of Legends doesn't want to cooperate. I have not tried downloading the game to the windows side and running it from there yet which is a possibility to try but I'd really much rather run this on the mac side.

@Arbystrider I don't expect this to be the baddest guy on the block but I don't expect it to perform worse than my internal GPU either. Other than "don't use the 970" I need to understand what is happening here bc even with suboptimal benchmarks it should still be better than the internal. @ti_padawan I tried unplugging the others and running it and I get the exact same FPS. Stays around 33 whereas the internal GPU will run at 60 although it will overheat after about 30-45 mins. It's just not making any sense. I am running VMWare fusion but not for these purposes. This is all on the mac side and when I turn on my comp and check system settings, it shows the 3 externals as being on the eGPU and the retina on the internal. Not sure why but mine has run like this naturally this from since the first time I plugged it all up.

Hi everyone, I've managed to build my eGPU and get it working great. I'm running 3 external monitors at 1080p with no issues at all on a Zotac GTX970 with the Akitio Thunder 2. The internal GPU is running my retina screen. The 970 is running the three externals. (I've confirmed this in the system settings). Here is my problem... when I go to play a game and put it on an external screen running on the eGPU... I actually get LOWER performance than if I run it on the retina screen under the native GPU. Any suggestions? Here's my setup: Macbook Air 13in Early 2014 1.7GHZ Intel Core i7 8GB 1600 mhz DDR3 RAM Intel HD Graphics 5000 1536MB Akitio Thunder 2 Zotac GTX970 EVGA 500W Power supply (connected to both the Akitio and the GPU) Running the latest Nvidia drivers already No issues booting up (other than it just being slower than without the eGPU connected) Used the automated scripting tool to set it up

Hello Everyone, First timer here and thank you for the amazing amounts of information you have all provided and gathered. Truly remarkable group of individuals. So I haven't seen where someone has done this yet, but I'm trying to build a single "box" to encapsulate all of my components both for my 3 external monitors plus their respective DVI/HDMI cables, as well as my eGPU setup. Effectively, this means I'd like to build using an adapter that does NOT come with the entire enclosure/chassis prebuilt. What I would like to do is have a single Computer Case/Tower to hold: eGPU adapter GPU with full length space in order to upgrade to the 10 Series when Pascal is compatible with Sierra. Power Source Surge protecter INSIDE the case to plug in all 3 external monitors and the power source Ability to upgrade to thunderbolt 3 when applicable At the end of the day I'm trying to build a single box with the only cords sticking out of it being a single Thunderbolt plug and a single power cable and maybe the capability to plug in a USB peripheral to the case as an added bonus. I've got everything pretty much figured out with the case, plugs, surge protector and all except I can't seem to find an eGPU adapter without the chassis included to convert from Thunderbolt to PCIE. I would really appreciate any insight or help for most importantly, if there is an adapter to suit what I want to do, and what would be the best eGPU with the least number of issues to use on the Mac side. My current setup: Early 2014 Macbook Air Mac OS Sierra 10.12.3 (beta) Thunderbolt 1 port 1.7 i7 8GB Ram 1600 MHZ DDR3 Intel HD 5000 500GB SSD VMware Fusion 8 3BenQ GL2460's Matrox TripleHead2GO Thanks in advance for your help and I'll be happy to share pics and tutorial on the project when I finish.
