opi5 and rpi5 would for sure run it might not even have to turn down settings .....anything previous not so much ....i can play COD on ultra settings on android but same hardware ....i dont know what 7dtd is written in but when compiling it should just be a simple flag like this :
mkdir build; cd build; cmake .. -DRK3588=1 -DCMAKE_BUILD_TYPE=RelWithDebInfo
make -j4
Or
# Toolchain file for cross-compiling for ARM64
set(CMAKE_SYSTEM_NAME Linux)
set(CMAKE_SYSTEM_PROCESSOR arm64)
And even if it turns out to be "meh" on those boards give it six months and your already ahead of the curve arm64 is only going to grow from here on out ......also cred of being like the only supercool game to play on aarch64 linux without needing wine or proton (i really do hate wine)
