I test on a nexus 7 2013 as my base(lowest) device and the game runs well on that, I still have hdr on(for the heightfog) but the other things you mention are done and there are no lights in the game only a skylight and height fog…Ill probably have to add a disclaimer that the game is for newer devices or keep limiting devices with texture format, I did notice there is a slight performance drop using ETC1 as opposed to ATC, I will experiment with a new lighting style and not using hdr in the next version and try to reduce the draw distance on the map for older devices im also using nativize blueprint assets, maybe its not optimized enough yet in 4.14 maybe its not even working on android lol although from the logs its being used…thanks for your testing, its invaluable to get some feedback as im planning to have a much more polished version of the game for 4.15
