Vsync_adjust = 2 This makes the video output draw to the screen as fast as possible, and can result in sub-frame lag consistently (independent of your controller and display's built-in lag). Here's a list of the options and what they do. To use a framebuffer adds a minimal amount of lag. So occasionally there is a little 'stutter' on the screen to make up for the frames going too fast and being adjusted. The game is still running at 60.6hz but the frames are sent at 60hz. Therefore, MiSTer has what is called a 'framebuffer'. Most modern displays work fine at 60hz, but some games run at 60.6 hz (like Donkey Kong for the arcades) which is a 'non-standard refresh rate'. vsync_adjustĪnother important option is vsync_adjust. There is a detailed explanation of video modes available in Advanced - Video Modes thanks to Wickerwaka. You can also use the ini-settings.sh script, it will tell you what option selects which resolution, so just select the right one for your display.

For most people they will probably want to use 1920x1080 resolutiono at 60hz, so my advice would be to change this to video_mode=8. 0 - 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - tells you that video_mode=0 will set you to 1280x720 resolution at 60hz. Alternatively you can run the ini-settings.sh script in the scripts folder, this has a simple interface to change options. Pretty much any text editor will be fine. We'll just focus on a couple here for now and you can dive deeper into things like CRT usage in the Advanced - CRT section.įirst, you can edit the settings in the MiSTer.ini file with windows Notepad, Visual Studio Code, Notepad++. In the MiSTer.ini file there are many video setttings to try. Here's an example video showing you how easy it is: Select the one you want and see if it looks good to you. They are easy to use, just open the OSD, press right, then go to video processing, and then 'Load Preset'. Video Presets were added so you can easily load a good-looking preset that will work in most situations.

There are lots of options to play with, here's some basic ones.

Also, you can use 5x overscan mode to push a 1200p image into 1080p for square pixels and nearly the original overscan of a CRT, depending on the game's resolution. You can change your resolution, modify the framebuffer to reduce input latency and video stuttering, add some video filters, use shadowmasks, and even gamma correction. Here's a description of some basic video customization features on the MiSTer.
