Well, I'm not too sure with all this mobile talk with realtime GI but HDRP doesn't really support mobile (It was being worked on). I think a lot of people are mixing things from their use of the Builtin renderer and that's why they are a lot more frustrated with the situation. - Built-in Renderer supports every platform and Enlighten (until 2022 since ) Built-in doesn't get new features just bug fixes until it's been replaced by URP). - HDRP initially had Enlighten support but it wasn't fully supported it just worked, it mainly supported the PLM. HDRP only supports compute capable devices, consoles, and PCs. - URP/LWRP never supported Enlighten but it supports all platforms. GI is also from PLM With this in mind, you can properly parse the info here and understand where others are coming from when they mention not worrying about mobile, etc. The rendering future of Unity is URP and HDRP/DOTS Hybrid (For both pipeline) Builtin will be dropped so most people here are already using HDRP or URP and if you understand the purpose of each pipeline you kinda get why things are going how they are. Your only frustration is that you don't have a replacement currently rather than what the new solution should support. The higher-end phones with compute could run HDRP but I guess this is more a future thing (most phones will have compute and a lot more powerful) unless your target today is just the higher-end phones and running a short demo rather than a full game with HDRP. URP is used for a wide range of platforms. If the new system is quite universal (HDRP and URP) then maybe mobile will have realtime GI as well. The only thing we have to go off right now was that Unite Copenhagen presentation and that was all RTX base.
