Not sure you can at this point, SSD helps but even people with them and good builds are having problems. The Reg I played it on last night is i5 9600K at 5.0ghz, 32 gb or ram, RTX 2080 super, and a 2tb 1800mbs ssd. And it crashed and jerked all over the place, there is just things they need to fix right now. Some people with far less powerful rigs then the one I played are having no problems while others cant even play. So we just have to wait on TaleWorlds for some fixes.
