Which apps should you install first?

You don't need all 10 immediately. Start with the ones that fit how you play.

Play with friends	Discord
Monitor temperatures and FPS	MSI Afterburner + HWiNFO
Record or stream gameplay	OBS Studio

A few tips before downloading

• Use official websites. In particular, MSI warns about fake Afterburner download sites. AfterburnerHow to use MSI Afterburner
• Avoid installing everything at startup. Hardware monitors, overlays, and launchers can consume resources or conflict with one another. OBS documents known conflicts involving some monitoring and capture tools. Known Application ConflictsGame Capture Troubleshooting
• Don't expect a magic FPS boost. Monitoring and benchmarking apps help identify problems, but actual performance gains depend on your hardware, drivers, and game settings.

My top three picks: Steam for gaming, Discord for communication, and MSI Afterburner for monitoring performance. Add OBS Studio if you record videos or stream.

All 10 apps have free core functionality, although some are more useful for particular setups than others.

Building and maintaining the ultimate PC gaming setup doesn't require a hefty software budget. From tracking frame rates and managing fragmented game libraries to capturing epic highlights and tuning your hardware, here are 10 essential, 100% free PC gaming apps that every gamer should have installed:

1. Steam

• What it is: The gold standard of digital game distribution.

• Why you need it: Beyond being the largest marketplace for PC games, Steam is a social hub, cloud-save manager, and workshop for community mods. Even if you buy games elsewhere, Steam's robust ecosystem, big picture mode, and controller support make it non-negotiable.

2. MSI Afterburner + RivaTuner Statistics Server (RTSS)

• What it is: The premier hardware tuning and on-screen display (OSD) suite. Top 10 Free Gaming Tools and Must-Have Software Every PC

• Why you need it: It allows you to monitor your GPU and CPU temperatures, clock speeds, and usage in real time. Paired with RTSS, it gives you a clean, customizable overlay to track your exact frame rates (FPS) and stutter metrics while gaming. (Works on all graphics cards, not just MSI!).

3. HWiNFO64

• What it is: Deep-dive hardware diagnostic and monitoring software.

• Why you need it: If you want a complete x-ray vision look at your PC's health, HWiNFO64 reads every sensor on your motherboard, CPU, and GPU. It’s invaluable for diagnosing thermal throttling, tracking voltages, and logging data after a long gaming session.

4. Discord

• What it is: The universal voice, video, and text communication platform.

• Why you need it: Whether you’re coordinating squad tactics in a competitive shooter or hanging out in community servers for your favorite indie titles, Discord is where the PC gaming community gathers.

5. Playnite (or Heroic Games Launcher)

• What it is: Open-source library managers. 9 essential apps to get started with PC gaming - Club386

• Why you need it: With games split across Steam, Epic Games, GOG, Battle.net, and Xbox apps, launchers get messy. Playnite unifies all your games and emulators into a single, gorgeous customizable interface. Alternatively, Heroic serves as a lightweight open-source client specifically built to merge Epic, GOG, and Amazon Prime gaming libraries. 9 essential apps to get started with PC gaming - Club386

6. OBS Studio

• What it is: Open-source video recording and live-streaming software.

• Why you need it: If you want to stream to Twitch/YouTube or just clip your best gameplay moments without heavy performance hits, OBS is the professional choice. Utilizing hardware encoding (NVENC or AMD equivalent), it delivers studio-quality captures completely free with zero hidden paywalls. Top 10 Free Gaming Tools and Must-Have Software Every PC

7. Display Driver Uninstaller (DDU)

• What it is: Deep-clean utility for graphics drivers.

• Why you need it: When upgrading or troubleshooting NVIDIA, AMD, or Intel graphics drivers, standard uninstalls often leave corrupted files behind. DDU wipes old drivers completely clean in Safe Mode, preventing mysterious game crashes and stuttering bugs.

8. DS4Windows / JoyToKey

• What it is: Controller mapping and emulation software.

• Why you need it: While Steam has native controller support, many games outside of Steam struggle with PlayStation or alternative gamepads. DS4Windows makes your DualShock/DualSense controllers seamlessly recognized as Xbox controllers, while JoyToKey lets you bind keyboard strokes to gamepads for older games.

9. CrystalDiskInfo

• What it is: S.M.A.R.T. hard drive and SSD health monitor.

• Why you need it: Modern games take up massive amounts of storage, and dying drives can cause horrific stuttering or sudden data loss. CrystalDiskInfo runs quietly in the background to alert you before your solid-state drives or hard drives fail.

10. NanaZip or 7-Zip

• What it is: Open-source archive and file compression utilities.

• Why you needit: PC gaming heavily involves extracting compressed files, custom game mods, and archives (.zip, .rar, .7z). Windows native tool can be slow, whereas 7-Zip (or NanaZip, optimized specifically for Windows 11) handles heavy files instantly without pesky pop-up ads or nagging upgrade fees.

Which of these utilities do you already have in your toolkit, or are you looking to optimize your PC for a specific genre like competitive shooters or streaming?
