Unreal Engine version 4.8 and later will now support the use of ES31 and AEP rendering on Tegra K1 devices. Please note that due to the limited number of devices that currently support ES31 and AEP rendering, very little performance and compatibility testing has been completed at this time. If you are developing a project that is aimed at using one of these devices, it is highly recommended that you perform extensive performance and compatibility testing to ensure that the device delivers your project in the manner you intended.
