I'm surprised the Uber devs didn't have a way to change the screen resolution from the game directly since most games do. Anyhow, I managed to do it pretty easily with some simple hacks but it requires a few things. Here's the steps. 1) Download NirCMD (h ttp://w ww.nirsoft.net/utils/nircmd.html) - scroll to the bottom of the page for the download link 2) Extract it to your Planetary Annihilation Folder (with the subfolders structure intact) 3) Create a simple batch file called "playpa.bat" in the Planetary Annihilation folder with the following contents: @echo off nircmd-x64\nircmd setdisplay 1440 900 32 start /b /wait bin_x64\pa.exe nircmd-x64\nircmd setdisplay 1920 1080 32 4) The 2nd line that shows "setdisplay 1440 900 32" is the resolution and color bits you want to set (32 = 32-bit color) 1440 = width, 900 = height. That's the resolution you want to use in the game. The 4th line is your usual/native resolution. Mine is 1920 x 1080 so I set it as such. What this batch file does is, sets the resolution to what you want first, launches the game - waits for it to terminate, then sets the resolution back to your native one. Have fun and hope that helps! P/S: Yes - i'm that CyberKewl - the one who made TAUIP and TAUCP for Total Annihilation back in the day
There's no need to actually change from your native resolution on modern hardware. See the Resolution Scaling setting in-game. Also see DSR and VSR for Nvidia and AMD respectivly. A scale of 133.33% is likely not going to be as crisp on a LCD display as the above methods (might also force a lower refresh rate).
That is true for the rendered game window- however the UI is always at desktop native resolution as per @mikeyh post. The suggestion by the OP is useful for much older hardware imo- as it allows the full game (UI included) to run at lower resolution without having to lower the desktop resolution when not in game. It will of course break alt - tabbing out of the applications, but it's a nice option for those with lower spec machines to potentially get a bit of a performance boost,
