PhysX, fury, and a weekend miracle
Zluda 6 release (run unmodified CUDA applications on non-Nvidia GPUs)
This scrappy tool lets AMD cards crash Nvidia’s party — and commenters are obsessed
TLDR: ZLUDA 6 is out, bringing early support for old PhysX game effects and better Windows help, making some Nvidia-only software work on AMD graphics cards. Commenters are split between retro-gaming excitement, AI curiosity, and delight at the irony of a hobby project stepping into a mess even Nvidia stirred up.
A niche graphics tool just dropped a big new update, and the crowd is treating it like a comeback episode with budget drama. ZLUDA version 6 helps some programs built for Nvidia gear run on non-Nvidia graphics cards, and the flashy headline feature is early support for old-school PhysX effects — the cinematic debris, smoke, and fire tricks that once made PC gamers drool. For AMD owners, that means some older games could suddenly look fancier or run faster. Yes, commenters immediately smelled chaos.
The loudest reaction wasn’t just “cool,” though — it was “wait, can this run AI stuff?” One user jumped straight to large language models, asking how this compares to Vulkan, because of course the internet sees a gaming breakthrough and instantly tries to turn it into an AI benchmark war. Another thread favorite was the project’s new vibe: the developer says commercial funding is gone, so ZLUDA is back to being a weekend hobby. Weirdly, that made people more affectionate, not less. One commenter praised the renewed focus on amusement, which is probably the most charming way possible to say, “fine, let’s build fun stuff instead of investor bait.”
And then came the jokes. A commenter pointed out that “Złuda” means mirage or illusion, which is basically the perfect name for software that makes one company’s apps appear to work on another company’s hardware. Meanwhile, the real spicy context came from users noting Nvidia had briefly flirted with dropping a certain old PhysX setup before backing off after backlash. Translation: the comments section is loving the irony that a fan-made workaround is now part of the conversation at all. It’s part underdog story, part retro-gaming soap opera, part “the community will absolutely test this on something ridiculous by tonight.”
Key Points
- •ZLUDA version 6 was released as a major milestone and is identical to preview build 6-preview.79.
- •The release adds pre-alpha support for 32-bit PhysX, enabling some older PhysX-based games to run better on AMD GPUs, though support remains incomplete.
- •Basic texture support was added, and the article says this is sufficient to make Blender work on ZLUDA.
- •Windows support was improved through better handling of missing ROCm-related libraries and a more robust zluda.exe loader that automates performance-library loading.
- •Recent machine-learning compatibility work was driven by PyTorch user traces and includes new instructions, compiler bug fixes, and performance-library improvements.
