I know of the thing where you can edit the shortcut properties of TPT to make it fill the screen, but that kills my CPU and loads terribly slow, also, the pixel graphics are lost with no compensation.
I know this may "break" saves, but in a way it won't, all it will do is increase the boundaries.
If the size of the powdertoy is about 800x600 now, I don't see why it would be bad if you increased it to the next size of 940x800
If you search this was suggested, maybe a million times now. No Get used to scale:2 or try kiosk. Yes it looks pixely but oh well. I find that scale:2 runs faster for me, anyway.
@baldboy_666(View Post) well slightly increasing the size won't be detrimental. the jump from 800x600 to 940x800 isn't that big after all.
I have a 1 ghz processor and half a gig of ram and I have a 128mb video card and I have always gotten 50 frames even when I build cities and complex structures, after some massive building I usually drop to 30, which is noticeable but not disappointing,
