cbong23 Posted October 18, 2015 Share Posted October 18, 2015 Hello all,This might be a noob question, but I've been able to set my egpu, but couldn't get it to work on internal LCD under OSX.Is there a special thing I have to do? Quote Link to comment Share on other sites More sharing options...
Dschijn Posted October 18, 2015 Share Posted October 18, 2015 You can only run rendering apps on the internal display.Another way is to start games on an external monitor (conencted to the eGPU), make them Windows mode and drag the window on the internal monitor (cant go fullscreen again, though…).

cbong23 Posted October 18, 2015 Author Share Posted October 18, 2015 You can only run rendering apps on the internal display.You mean external display?Just to clarify. Under OSX, I HAVE to use external monitor? (not thunderbolt display but monitor with DVI/HDMI input) Quote Link to comment Share on other sites More sharing options...
Dschijn Posted October 18, 2015 Share Posted October 18, 2015 No, like I said:Internal display can use the eGPU for rendering apps, like Octane.But in general you HAVE TO use an external monitor in OSX with the eGPU. DVI, HDMI, DP… one of the ports that the GPU of the eGPU has. Quote Link to comment Share on other sites More sharing options...
euqlaog Posted October 18, 2015 Share Posted October 18, 2015 The concept of rendering means apps such as Octane and Indigo renderer. There are number of apps which can utilise offscreen OpenGL and computing power of OpenCL or CUDA. Adobe After Effects, Photoshop, Premiere, Final Cut Pro X etc. In this case, an external monitor is not necessary. But I don't know how well Adobe apps support external GPGPU on current release of El Capitan. CUDA drivers may not be always compatible. There was a thread about this. For OpenGL gaming, an external monitor is necessary.But that’s not the whole story. I can run some games and Valley benchmark purely on the internal retina screen accelerated by eGPU via TB port only, other display cables disconnected. The proof of concept is done, but far away from any practical for now. Quote Link to comment Share on other sites More sharing options...
Tech Inferno Fan Posted January 12, 2016 Share Posted January 12, 2016 Here's @w4vz' relevant nugget from https://www.techinferno.com/index.php?/forums/topic/6962-2012-15-macbook-pro-gtx97010gbps-tb1-akitio-thunder2-win10osx1011-w4vz/&do=findComment&comment=131467 Quote under OSX you have to use an external screen; no choice. Under windows you can use optimus. That said I experimented a while ago and I think you can get accelerated internal screen under OSX with mirror mode and a dummy plug on the eGpu because it worked for me if I started a game on mirror mode with my screen then disconnected it I could still play on the internal screen without performance loss. Haven't tried to dig any deeper yet. Quote Link to comment Share on other sites More sharing options...
hramos90 Posted January 30, 2016 Share Posted January 30, 2016 Hey guys I'm also curious about this questions as I have had in mind the whole time I was looking into eGPU's to game on my internal LCD. Is there no solution for this yet at all? @Dschijn @Tech Inferno Fan Quote Link to comment Share on other sites More sharing options...
Dschijn Posted January 30, 2016 Share Posted January 30, 2016 No propper solution available yet imho. Quote Link to comment Share on other sites More sharing options...
