Simply based on the vRAM requirement it would seem that no, the RX 9070 (with "only" 16GB of vRAM) will not handle the 1024x or 2048x texture packs, unless they factor shared/virtual graphics memory in with the dedicated, and even then the system memory requirements are steep.

Why not just download it and try it out? Either it'll work or it won't.
