on old pc:1004 (cpu:pentium 2.40 dual what ever... and a stupid outdated 256mb G100 nvidia card + 2GB ram
new one:I5 2500k 3.40hz quad core 4gb ram ati radeon 5000 series 1765
Well the engine is by "insertnamehere" but i made it better and stable by turning springs from legacy mode 3 to 2 and making pistions and flywheel heavier and i forgot... try turning hings legacy mode to 0 then the engine should be stable
