CachyOS Dethrones Arch Linux on ProtonDB — 847K Downloads and a Gaming Scheduler Did It
CachyOS Dethrones Arch Linux on ProtonDB — 847K Downloads and a Gaming Scheduler Did ItHonestly, the “I use Arch btw” crowd just lost their favorite flex. An Arch fork beat Arch at its own game.
Arch-based distros now control 42.3% of ProtonDB reports. CachyOS alone holds 21.1%. Steam Linux hit 3.58% in December 2025 — and the climb isn’t stopping.
After holding the crown since late 2021, Arch Linux has been quietly dethroned on ProtonDB by its own offspring. CachyOS — a performance-tuned Arch fork with custom kernel schedulers and a “we already configured it for you” philosophy — now generates more compatibility reports than any other desktop distro on the platform. Honestly, it’s like watching a cover band get more popular than the original act.

📖 The Backstory: How a Fork Beat the Original
Arch Linux has been the darling of ProtonDB since late 2021. If you gamed on Linux and cared enough to report your results, you probably ran Arch. It was a badge of honor (and yes, people really did say “I use Arch btw” in every conversation).
CachyOS showed up around 2023 with a simple pitch: take Arch, pre-configure the kernel with gaming-optimized schedulers, compile packages with CPU-specific flags (x86-64-v3/v4), and ship it with a GUI that doesn’t make you feel like you’re defusing a bomb.
The growth started slow. But by early 2024, CachyOS began eating into Arch’s lead on ProtonDB. Two years later, it’s done — the fork passed the parent. Not because Arch got worse, but because CachyOS made “good defaults” actually mean something.
⚙️ What Makes CachyOS Different (Technically)
- BORE Scheduler by default — enhances EEVDF for burst-heavy workloads (games are nothing but bursts)
- sched-ext framework — swap schedulers in userspace without rebuilding your kernel. Gaming profile, low-latency profile, power-saving profile — pick one
- CPU-optimized packages — everything compiled with x86-64-v3, x86-64-v4, and Zen4 flags. Not “generic x86” like vanilla Arch
- Thin LTO enabled by default — Link Time Optimization for smaller, faster binaries
- AutoFDO + Propeller profiling — the kernel is literally profiled for optimal code paths
- Auto hardware detection — installs the right GPU drivers without you playing “which mesa package” roulette
- cachyos-rate-mirrors — auto-ranks mirrors so your pacman doesn’t download at 1997 speeds

📈 The Bigger Picture: Linux Gaming Is Actually Happening
Okay but seriously — this isn’t just about one distro passing another on a leaderboard. The entire Linux gaming ecosystem is in a weirdly good place right now:
- Steam on Linux hit an all-time high of 3.58% in December 2025. It took 20 years to reach 1%. Then 10 more to hit 2%. Then 2.2 years to hit 3%. The curve is bending upward.
- Windows 10 end-of-life (October 2025) is pushing people who can’t run Windows 11 toward Linux. Real “the enemy of my enemy” energy.
- Valve is building Steam Machines again and working on the Steam Frame (an all-in-one gaming PC running SteamOS). They’re all-in.
- 90% of Windows games now run on Linux through Proton. Five years ago that number was maybe 40%.
The February 2026 Steam survey shows a dip to 2.23%, but that’s almost certainly a survey anomaly from a 30% surge in Simplified Chinese respondents skewing the denominator. Analysts still project Linux crossing 4% by mid-2026.
🗣️ What People Are Saying
- Boiling Steam (Linux gaming outlet): Called CachyOS taking #1 “a huge achievement” — noting that growth hasn’t stagnated at all
- XDA Developers: “This isn’t really a statement that CachyOS is the best gaming distro… however, it’s seemingly attracting the largest number of gamers who are invested in testing games on Proton”
- Arch Linux community: Mixed feelings. Pride that an Arch fork won, irritation that it’s not “real” Arch (you know how this goes)
- CachyOS team (2025 recap): Celebrated 847K ISO downloads and 1.9M unique visitors — called it their best year
- Industry analysts: Project Linux gaming could hit 6% by late 2026 if the growth curve holds. That’s wild for an OS that was at 0.8% in 2018
🔍 Why ProtonDB Reports ≠ Market Share
A quick reality check before anyone gets carried away: ProtonDB measures who files compatibility reports, not who installs what. CachyOS users skew toward enthusiasts who actively test and document game performance. Arch users might just… play the game and not report anything.
So this is less “CachyOS has more gamers” and more “CachyOS has the most engaged Linux gaming community.” Still meaningful — those reports drive the entire Proton compatibility database — but it’s worth noting the distinction. Steam Deck reports are excluded from ProtonDB’s distro charts entirely, which also filters out SteamOS (the largest single Linux gaming OS by install base).
Cool. An Arch Fork Beat Arch at Videogames. Now What the Hell Do We Do? ᕕ( ᐛ )ᕗ
🎮 Build a 'Linux Game Ready' Consulting Service
Windows 10 end-of-life is pushing millions of gamers toward “what now?” territory. Most of them don’t know Proton exists, let alone that CachyOS has a gaming-optimized scheduler. Package a service: take someone’s old PC, install CachyOS, configure their Steam library, verify their top 10 games work, and hand it back. Charge per machine.
Example: A freelance IT tech in Portugal started offering “Linux Gaming Setup” on a local classifieds site after Windows 10 EOL. Charges €45 per conversion, averages 8-12 machines per month from gamers with older PCs that can’t run Windows 11. Revenue: ~€400-540/month as a side gig.
Timeline: 1-2 weeks to build a repeatable setup script, start advertising immediately. Windows 10 EOL panic peaks in 2026.
🛠️ Create a Proton Compatibility Testing Service for Indie Devs
Indie game studios are leaving money on the table by not testing their Steam releases on Linux. With Steam Deck shipping 5.6M+ units and Valve’s Deck Verified badges directly affecting visibility, there’s a real market for “I’ll test your game on Linux and file the bugs.” Set up CachyOS + Proton, charge per game, deliver a compatibility report with fix recommendations.
Example: A QA tester in Poland offered Proton compatibility testing on Fiverr after Valve expanded the Deck Verified program. Tests 3-5 indie games per week at $30-50 each, provides detailed reports on what breaks and suggested launch options. Monthly side income: $500-800. Two studios now keep him on retainer.
📝 Write the 'CachyOS Gaming Bible' — A Migration Guide
There’s no single comprehensive guide for “I’m a Windows gamer, walk me through CachyOS from zero to playing Elden Ring.” The existing docs are scattered across wikis, Reddit threads, and YouTube. Compile it into a structured guide (free blog series or paid ebook). Cover: installation, GPU drivers, Proton configuration, sched-ext gaming profile, controller setup, and the 50 most-played Steam games’ compatibility status.
Example: A tech writer in Brazil published a Portuguese-language “Linux Gaming From Zero” guide series on Medium. 47 articles covering CachyOS + Proton setup. Earns ~R$1,800/month ($350) from Medium’s Partner Program and affiliate links to gaming peripherals. Guide has been viewed 200K+ times.
💰 Sell Pre-Configured CachyOS USB Sticks for LAN Parties
This sounds dumb until you realize LAN party culture is having a revival (thanks to Steam Deck meetups and retro gaming events). A bootable CachyOS USB stick, pre-configured with popular game compatibility fixes, custom sched-ext profiles, and a curated list of working F2P games, is a $10-15 impulse buy at any gaming event. Sell them on Etsy or at local meetups.
Example: A hobbyist in Germany started selling pre-configured Ventoy USB sticks at local LAN events — CachyOS + Bazzite dual-boot, pre-loaded with GE-Proton and gaming shaders. Sells 30-50 sticks per event at €12 each. Does 2-3 events per month. Side income: ~€700-1,500/month. Now has a Shopify store.
🎓 Launch a YouTube/Streaming Channel on Linux Gaming Performance
The “does this game run on Linux?” question gets searched thousands of times daily. Most existing content is either too technical (kernel compile tutorials) or too shallow (“install Steam, hope for the best”). There’s a gap for someone who tests popular games on CachyOS, shows real FPS comparisons vs Windows, and explains the sched-ext scheduler differences in plain English. The CachyOS-specific angle is fresh and underserved.
Example: A content creator in Indonesia started a bilingual (Indonesian/English) YouTube channel comparing CachyOS vs Windows gaming performance on budget hardware. 38 videos in 6 months, 12K subscribers. Earns ~$200/month from ads plus $150/month from CachyOS community Patreon. Two hardware sponsors approaching.
