'Half-Life 2 RTX has shrunk from 80 GB to 50 GB': RTX Remix 1.5 update shrinks file sizes, and also starts letting in AI agents

Overview & Key Takeaways

I suppose that's one way to bring an old game up to date…

If you're on a budget, now is really not the time to upgrade your gaming rig's storage. The memory supply crisis is driving up the price of SSDs, meaning many will have to make do with what they've already got for as long as possible. Even older games can still have large file sizes, especially if they're enjoying a fresh lick of path-traced lighting. Thankfully though, RTX Remix 1.5 may make juggling your backlog a little easier.

Just in case you've not ventured out from under your cool mossy rock since 2004, RTX Remix is Nvidia's attempt to refine the dated visuals of yesteryears' games. The open-source modding platform allows users to update the look of their favourite games with generative AI tools, neural rendering tech, and ray tracing. Unfortunately, all of that fresh tech tends to expand the file size of a 20 year old game. The latest update addresses that file size creep.

RTX IO is Nvidia's high-performance storage tech, which introduces a number of improvements including cutting down game file sizes. The company says, "Thanks to [the RTX Remix 1.5] update, file sizes have dropped significantly: Portal with RTX has been reduced from 25 GB to 17 GB, while Half-Life 2 RTX has shrunk from 80 GB to 50 GB."

This compression is now available inside the RTX Remix packaging workflow. On top of whittling down game file sizes, RTX IO also reduces CPU overhead and speeds up loads.

The 1.5 update introduced a number of other improvements, including 'smooth normals' so that lower poly geometry looks less obvious with a path-traced lighting mod. Speaking of lighting, modders will also enjoy easier to use viewport light controls. Apparently, "existing light manipulators are easier to manage through a unified viewport lights menu, with persistent toggles for manipulator visibility and intensity controls."

Now, RTX Remix wouldn't be an Nvidia product without at least one more look-in from AI integration (in case you're still living in 2004, the data centre segment of Nvidia's business made $75.2 billion last quarter alone). The company writes, "Because [the modding] pipeline relies heavily on defined, manual steps, it is perfect for an AI agent to lend a hand."

Specifically, Nvidia published a selection of "text-based instruction files that provide specific functional context to AI coding agents" called 'RTX Remix Skills'. The argument is that letting an AI agent handle some of the technical heavy lifting lowers the barrier to entry for human wannabe modders who are not well-versed in either C++ or Python code languages. I'm all for making the technical more accessible…but I'm also incredibly wary of AI agents sticking their metaphorical foot in modders' work.
