Fixing input lag in Terraria/TML. Solution took me about 30 hours of research.
I have been suffering with unbearable input lag for about a week. I have been unable to play Calamity Infernum properly due to the insane amounts of input lag, somehow I got all the way up to DoG before I finally decided to fix the problem once and for all. I have tried scouring reddit threads and forum posts to no avail, however, I have finally found the solution.
Input lag is caused by Terraria forcing V-sync on in order to make the game "smoother" aka unplayable which comes at a cost: huge input lag. If you are on and AMD/Nvidia GPU this can be fixed simply by disabling V-sync via the GPU control panels. However, some people like me don't have the luxury of a dGPU so we are unable to force it off.
I recently discovered a program called Special K https://www.special-k.info/ which can force V-sync off on any system for any game. It's as simple as downloading the app and launching TML thru it. Next just navigate to the Display section at the top and turn the V-sync option to "Force OFF" and make sure frame skip is set to subtle in your in game settings....
Constant Errors
I'm trying to fix the syncing issue on the side, I'm not sure what's going on but I now have an issue with reloading mods every time I want to remove or add a mod.
Mods are not downloaded via the mod browser
the first couple of megabytes of the mod are downloaded and then the download freezes, this only happens with some mods (such as recipe browser and magic storage), this has never happened before
