RenoDX is an open-source framework for creating targeted graphics mods for DirectX games. It solves the problem of generic, one-size-fits-all post-processing by allowing mods to be built around individual games' rendering pipelines for precise upgrades like HDR output and shader replacement. It's for modders and players who want to enhance specific games with deep, persistent, and game-aware visual modifications.

A pay-to-rank board where the leaderboard is a self-playing snake. Every cell of its body is a startup, ordered by how much it has paid. Bid higher than the listing above you and you take its place — bid above everyone and you take the head. Rank is total dollar committed, so bids stack and climbing only ever costs you the difference. Ties go to whoever got there first, which means matching the leader buys you #2 not #1. New spots start at $5 and board is brand new — the head is cheap right now.
