Just installed the latest Beta on my brandnew notebook (Intel Core i7 1165 with Intel Iris Xe integrated graphics. Under Preferences - System - Memory and CPU - GPU Configuration I can only choose OpenGL as GPU processing mode.
And under Deliver - Custom settings i can only choose h.264 for .mp4 files.
I wish I could render my uhd footage from my sony fdr-ax53 with hardware acceleration / intel quick sync support / hevc encoding. Hoped it would be possible as it was pronounced that hevc de-/encoding would be possible on supported intel platforms.
