Fixes
- The Witcher 3 Remastered: Low FPS and Stuttering on PCFixThe Witcher 3 Remastered tanks framerates on PC largely because of NVIDIA HairWorks, which CD PROJEKT RED says to disable. Here is that fix and what else to check.Last verified October 2026
- Battlefield 6 and other anti-cheat games crash seconds after launch on Windows 11 KB5124010FixGames with anti-cheat crashing to desktop seconds after launch trace to KB5124010, an optional Windows 11 preview update from 22 September 2026. Removing it is reported to stop the crashes.Last verified September 2026
- Steam shows one Xbox controller as two, and every input registers twiceFixOne Xbox controller listed twice in Steam, with every press registering twice, is a client bug Valve fixed on 21 September 2026 - but so far only in the Steam Client Beta.Last verified September 2026
- Monitor won't wake from sleep on DisplayPort after an NVIDIA driver updateFixNVIDIA confirmed its Release 615 drivers could stop DisplayPort monitors waking from sleep, and fixed it in 617.14 on 22 September 2026. How to tell if that is your black screen.Last verified September 2026
- Steam Client WebHelper (steamwebhelper.exe) using high CPUFixUpdate Steam first — Valve fixed a Library-tab cause on 6 September 2026. Then find which view drives the load. It is not a Windows update problem.Last verified September 2026
- DLSS 5 Neural Rendering Missing? What Actually Enables ItFixDLSS 5 neural rendering needs three things at once: an RTX 50 Series GPU, driver 616.64 or later, and a game that integrated it. Here is how to tell which one you are missing.Last verified September 2026
- Judgment, Lost Judgment and Virtua Fighter 5 R.E.V.O. won't launch after the NVIDIA 616.56 driverFixNVIDIA fixed this in Game Ready 617.14 on 22 September 2026. Update the driver — the rollback that was the only answer through 616.92 is no longer needed.Last verified September 2026
- Assassin's Creed Shadows crashes to desktop after the NVIDIA 616.56 driverFixStill unfixed in NVIDIA 617.14 of 22 September 2026, where it is the only open issue left. Rolling back to a pre-616.56 driver remains the only workaround.Last verified September 2026
- Virtual display stops working after the NVIDIA 616.56 driverFixNVIDIA's 616.56 driver broke virtual display creation, which breaks headless Sunshine, Apollo and Moonlight streaming. WHQL driver 616.92 now contains the fix.Last verified September 2026
- "Prefer maximum performance" does nothing on NVIDIA 610.88 through 616.92FixNVIDIA listed this open from 610.88 to 616.92. It vanished from the 617.14 notes without being listed as fixed — worth trying, but not yet a confirmed fix.Last verified September 2026
- RGB Lighting and Fan Control Stopped Working After inpoutx64 Was BlockedFixinpoutx64 no longer loads, so lighting and sensor tools lose SMBus access to RAM and motherboard controllers. How to tell what disabled it, and why updating the utility beats re-enabling it.Last verified September 2026
- Apex Legends and Starfield crash on Radeon RX 9000 cards after Adrenalin 26.8.1FixAMD fixed both crashes in Adrenalin 26.9.1 on 3 September 2026. The rollback to 26.7.1 that most guides still recommend is no longer needed, and never worked reliably for Apex.Last verified October 2026
- Smart Access Memory Turns Itself Off After an AMD Driver Update on Windows 10FixAMD lists Smart Access Memory switching itself off after a driver install on Windows 10 as an open known issue. Nothing warns you — here is how to check and switch it back on.Last verified September 2026
- Screen flickering and dark flashes after the NVIDIA 616.56 driverFix616.92 fixed the browser flicker NVIDIA documented, and 617.14 of 22 September does not address the wider 8-bit flicker. For that, 10 bpc or a rollback is still it.Last verified September 2026
- Smart App Control is blocking a game, launcher or modFixSmart App Control blocks unsigned code by default, which catches mods, older launchers and tools. Find out what it blocked before you switch it off — you may not get it back.Last verified September 2026
- Game stutter and Memory integrity on Windows 11FixWhether disabling Memory integrity helps your frame times depends on your CPU generation — Microsoft says so itself. How to check before you trade away a security feature.Last verified September 2026
- G-Sync or FreeSync not working in borderless windowed modeFixVRR engages in full screen but not in a borderless window. Four Windows and GPU settings decide this, and the one most guides skip is Optimizations for windowed games.Last verified September 2026
- Game runs on the integrated GPU instead of the NVIDIA oneFixSetting the preferred GPU in the NVIDIA Control Panel does nothing on modern Windows — the OS overrides it. Here is the setting that actually decides, and how to check it stuck.Last verified September 2026
- HDR looks washed out or grey in games on Windows 11FixGrey blacks, flat colour and a dull desktop after turning on HDR in Windows 11. Work out whether HDR is actually engaged, then fix the brightness slider, Night Light and calibration.Last verified September 2026
- Games crash with EXCEPTION_ACCESS_VIOLATION after Windows 11 KB5121003FixMicrosoft resolved this on 26 August 2026 by blocking the inpoutx64 driver that RGB and fan-control utilities install. What to do if the block has not reached your PC.Last verified September 2026
- Game Audio and Voice Chat Come Out of the Same DeviceFixWindows already keeps a separate default for voice apps — most people never find it. Set the headset as the Default Communication Device and voice chat splits off on its own.Last verified September 2026
- Game Shows a Black Screen on Launch but the Audio PlaysFixWorking audio proves the game is running and rendering. The picture is going somewhere you cannot see — another display, an unsupported mode, or an HDR mismatch.Last verified September 2026
- Game Crashes When You Alt-Tab on Windows 11FixAlt-tab crashes are a lost graphics device, not a broken game. Exclusive fullscreen and laptop GPU switching cause most of them — and disabling Fullscreen Optimizations makes it worse.Last verified August 2026
- Controller Works in Steam but Not in the GameFixSteam Input delivers your controller by injecting a virtual Xbox pad through the Steam Overlay. If the overlay never hooks the game, Steam sees the pad and the game does not.Last verified September 2026
- Microphone Works in Discord but Not in Your GameFixWindows keeps two default microphones, not one. Discord asks for the communication device and most games ask for the default device — if they differ, only one hears you.Last verified September 2026
- Discord Screen Share Shows a Black ScreenFixA black Discord stream is a capture problem, not a Discord bug. Exclusive fullscreen and privilege mismatches are the usual causes — audio keeps working, which is the clue.Last verified August 2026
- Game Stuttering After an NVIDIA Driver UpdateFixStuttering right after a driver update is often shader caches rebuilding, not a bad driver. Give it a few sessions before rolling back, then check GPU scheduling.Last verified September 2026
- Xbox Controller Won't Connect to PCFixA controller that pairs to a console forgets the PC, and vice versa — it only remembers one wireless host. Check pairing mode first, then re-pair.Last verified August 2026
- Steam: "Failed to Start Game (Missing Executable)"FixYour antivirus almost certainly quarantined the game's .exe as a false positive. Restore it and exclude the game folder, then verify the files.Last verified August 2026
- Steam Game Won't Launch After "Preparing to Launch"FixThe game isn't failing to start — it's starting and crashing instantly. Verify the game files first, then rule out overlay and background software conflicts.Last verified August 2026
- Steam: "Failed to start game (app already running)"FixSteam thinks the game is still open because it crashed without telling Windows. End the leftover process in Task Manager, then verify the game's files.Last verified August 2026
- Steam Disk Write Error: How to Fix ItFixA Steam disk write error usually means the library folder's write permissions broke, not that your drive is failing. Repair the library folder first, then work down.Last verified September 2026
Compatibility
- Does FSR 4 work on Radeon RX 7000 cards?PartiallyYes for the upscaler, no for the rest. FSR Upscaling 4.1 reached RX 7000 in Adrenalin 26.6.2, but ML frame generation stays RX 9000-only and RX 6000 waits for 2027.Last verified September 2026
- Do PC games work on Snapdragon Windows on Arm laptops?PartiallyPartly. Most single-player games run under Prism emulation, but kernel-level anti-cheat blocks many online games — Windows cannot emulate drivers.Last verified September 2026
- Does HDR work with Steam Remote Play?PartiallyYes, but only from a Windows host with NVIDIA or AMD encoding to an HDR client set to Enhanced 1080p or 4K. Valve's Remote Play docs never mention HDR.Last verified September 2026
- Does DLSS 4 work on RTX 30 and RTX 40 cards?PartiallyMost of DLSS 4 reaches older RTX cards, but the headline frame multiplier does not. What RTX 20, 30 and 40 owners actually get, what they do not, and how to turn it on.Last verified September 2026
- Do PC games require Secure Boot on Windows 11?PartiallyMost games do not care about Secure Boot. A growing set with kernel anti-cheat — Battlefield 6, VALORANT — refuse to start without it. What is required, and what turning it on costs you.Last verified September 2026
- Does Hardware-Accelerated GPU Scheduling Improve Performance?PartiallyMicrosoft's own position is that you should not notice a significant change. It is a latency feature, not the free frame rate boost it gets recommended as.Last verified September 2026
- Does the PS5 DualSense Controller Work on PC?PartiallyIt works as a gamepad, and through Steam you get gyro and the trackpad too. Adaptive triggers are the catch — they only work in games whose developers built them in.Last verified September 2026
- Does a Bluetooth Headset Microphone Work on a PC?PartiallyYes, but with a catch most people meet the hard way: on classic Bluetooth, turning the mic on drops your audio to mono. Only Windows 11 24H2 with LE Audio avoids it.Last verified September 2026
- Does an Xbox Controller Work With Windows 11?YesYes — over USB on every model, but Bluetooth only works on newer controllers, and headsets and chatpads stop working when you connect that way.Last verified August 2026
About PC gaming pages
What is collected here
Every published fix and compatibility answer tagged PC gaming, newest first. A page appears here whenever PC gaming is one of the things it affects, so pages that span several areas show up under each of them rather than only the first.
Fixes and compatibility answers are different things
A fix addresses something that is broken and walks through resolving it. A compatibility answer addresses whether two things work together at all, and opens with yes, no, or partly. They are listed separately because the question you arrived with determines which one helps.
Ordering and dates
Within a page, fixes run safest-first: the reversible steps come before the invasive ones. Across this list, pages carry either a verification date, meaning the claims were re-checked against their sources, or an updated date where no re-check has run yet.
The rules behind all of this are written down in the editorial standards, and the publishing system enforces them. Found a fix that is wrong, outdated, or unsafe? Tell us — corrections are handled before new pages.
