I'm using a Dell Inspiron, model number 3581, i3 7020u, 8 gigs of ram, Mesa Intel HD Graphics 620, I was using the latest singleplayer version for the post's date. Unity games are usually no issue under wine.
Sorry for the late reply, looking at your hardware it looks like your system can only handle well optimized and/or casual games, which my game isn’t; it’s a (manually) unoptimized game (often the optimization is completely in the hands of the Unity compiler) with a big open world. The graphics might not be top tier, granted, but the quantity of objects in the game can cause many systems to have a hard time. For me, my old HP laptop that I had owned for 6-7 years now which has no good graphics card or anything can stretch to a decent 30 fps on low/mid graphics settings. I’ve done everything to allow people to have access to the lowest settings but it doesn’t appear to help and some optimizations I’ve made only seem to help players with good graphics cards. Another thing that could possibly cause the bad performance is the code, which I might improve nearing the official launch of the game, and if that doesn’t help, I don’t thing I can do much. Either way thank you for your feedback and time, I appreciate it!
