I wish I could wear pyrovision items without turning on pyrovision
Steam\steamapps\common\team fortress 2\tf\cfg
Open mtp.cfg (if it doesn't exist, create it) and change it to this
"VisionFilterShadersMapWhitelist"
{
}
Disables the major visual effects of Pyrovision on all maps, all you'll be left with is particle effects, strings of christmas lights on maps, the "helium-enhanced" voice lines, and people laughing when they die
