That's exactly what I tried but there is no 800x600 or 1024x768 resolution available,I have: 320x240 (I think),640x400 (works good but looks real ugly and most text is unreadable) and then I have 1280x720 and from here onwards it just lags...
There is currently (as of 1/9/17) one way to get good fps. Its by selecting 320x300 in full screen mode. I guarantee you it will make your game run faster, but you still wont see the words and numbers clearly. you might be able to make it out a little bit, but that's the only way.
Well as I said it is playable on 640x400 (fullscreen) so there's no reason to choose lower resolutions but maybe if I select 640x400 and a better graphics quality setting?
Can you help me if i change the screen resolution to any thing when i enter the game it resets to 1366 x 768 which makes my game lag but graphic quality is working fine the resulution will only not reset if i click on windowed.
