Move Pre-Render Phase [~25% Performance Boost]

This FastFlag moves the Pre-Render task to an off thread after all other tasks are completed. By default, Pre-Render runs first, forcing the render thread to wait until the Pre-Render process finishes before it can start rendering a frame.

With this FastFlag enabled, Pre-Renderer is executed while the main thread is processing the previous frame. This adjustment allows the main thread to proceed without waiting for Pre-Renderer, leading to increased framerates at the expense of some frame latency.

This flag is most effective in CPU-bound scenarios.

Invisible 1

Stops the physics on your character froms sending to the server so your character doesn't move for the server. You can move on your client.

{
    "DFIntS2PhysicsSenderRate": "-30"
}

Invisible 2

Locks your character's position on the server to (0, 0, 0), having the side effect of turning you invisible. This only affects the server and other clients, not you. server-sided things that rely on your position, like clicking to get tools, will not function. In some games these can be abusable. Here is a list of them: Link

{
    "DFIntGameNetPVHeaderTranslationZeroCutoffExponent": "10"

Teleport ragdolled bodies to 0,0,0

this doesn't work in every game with ragdolls

the teleporting is clientsided, no one else can see them

Restricts the client from sending any physics-related information. This means other people can topple you over.

Fullbright 2

same stuff needed as fullbright but its better, fullbright 1 and 2 will let you noclip a bit inside a wall, be-aware.

tip: change the DFIntDebugFRMQualityLevelOverride fflag to 0 when you dont want quality 1 and wanna change it in game, best to hide ur fullbright while someone is watching.
