Windows 10 April update act like Nvidia optimus?
Anybody using Amd radeon card as egpu can confirm this ?
The spec-list is missing crucial information on which internal graphics card this iMac has. I looked up iMac13,1 which is a 21.5" model. I believe he replaced the stock i3 with an i7-3770K and runs Intel iGPU in this iMac. Therefore internal display acceleration by the eGPU is possible in Windows.
Still doesn't answer the OP's query as to whether AMD eGPUs get this feature. Though being a Windows rather than Nvidia feature it would make sense this would also apply to AMD eGPUs.
Thank you @nando4. This is a huge development if others can confirm on newer Thunderbolt 3 iMacs!
Guys, let me explain how the new features in Win 10 April 2018 Update (also known as 'Redstone 4") works. There are actually 2 different features here:
- So called "Graphics Settings", which allows the end user to set DirectX application/GPU affinity (meaning allowing the user to profile the application to run either on integrated GPU or discrete GPU), similar to what AMD Radeon Settings Switchable Graphics tab does: https://support.amd.com/en-us/kb-articles/Pages/DH-017.aspx (of course AMD solution is far more sophisticated, and unlike OS Graphics Settings, works with most of APIs - OpenGL, Vulkan, etc.)
- the second feature is much more interesting, and it was designed specifically for eGFX ecosystem.
- With earlier versions of Win10, Microsoft Hybrid Graphics was restricted to only internal integrated GPU and internal dGPU; when you connect an eGFX to a laptop with both iGPU and dGPU, you could not use eGPU to accelerate applications on laptop's internal panel
- With April 2018 update, now when you connect eGPU to the same laptop, iGPU and eGPU go in to Hybrid Graphics mode even though there is an internal dGPU, and now you can use eGPU to accelerate apps on the laptop screen.
The new OS feature is graphics vendor agnostic by design, and AMD graphics drivers work very well with both internal dGPU being AMD or NVIDIA.
What this new feature is NOT: if the laptop has dGPU only, it wont work as by definition Microsoft Hybrid Graphics requires an integrated GPU.
All of the above has been verified with regular Windows 10 laptops. Spoiler alert: a better AMD Graphics driver for Win10 Spring 2018 Update is coming this week
So,we are not limit to Nvidia cards to use internal screen anymore.
That's good news.
Obviously that will happend without any compression,but still it is a big deal.
Thanks everyone for the answers.
I can confirm this, using the graphics setting in win 10 April 2018 update it fixed my problem, well fixed the problem of using the graphics card for games , but I’m experiencing performance issues l, I don’t know if it’s related.
