The PS5 Pro just enabled PSSR by default in beta, and the Ubisoft Ghost Recon Wildlands re-release ships as a native 4K and 60FPS version. Consoles quietly caught up because upscaling stopped being a shortcut and became the point. On PC you have had these tools longer, in more forms, and mostly for free. This piece is the seven desktop apps we use to hit 4K and 60FPS in games that would otherwise stall on our GPUs, from Lossless Scaling’s game-agnostic upscaler to the driver-level features you already own.
We tested each on a Windows 11 gaming PC with an RTX 4070 and a Ryzen 5 desktop with an RX 7800 XT. Games ranged from Cyberpunk 2077 (a stress test) to Baldur’s Gate 3 (an optimization contrast) to Elden Ring (a frame-cap benchmark). These are the best desktop apps for 4K and 60FPS PC gaming in 2026, judged by how many frames they add per dollar and whether they play nicely with anti-cheat.
What to look for in a PC upscaling stack
Modern upscaling on PC has four layers, and every game supports a different subset. The right toolkit gives you a fallback for each:
- Driver-level upscaling (DLSS on NVIDIA, FSR on AMD, XeSS on Intel) is the cleanest but requires game support.
- Game-agnostic upscaling (Lossless Scaling, Magpie) works on anything that runs in a window, at the cost of some latency.
- Frame generation doubles rendered frames without more render work; smoothness comes with latency added.
- Frame limiting and monitoring (RTSS, Afterburner, powercfg) keeps the GPU from cooking itself hitting 300 FPS in a menu.
Never stack more than two of these at once. Layering an in-game FSR pass with Lossless Scaling then Reshade CAS on top gives you a soft, laggy image.

The apps
1. Lossless Scaling — Best game-agnostic upscaling and frame generation
Lossless Scaling is a $7 Steam app that runs an upscaler on any windowed game, plus a frame-generation pass that can double the perceived frame rate. On an RTX 4070 we took an unoptimized Steam game from 40 FPS at 1440p to a stable 60 FPS at 4K with LS’s own LS1 algorithm plus FSR sharpening. It is the pick for old games and indies that never got DLSS support.
Where it falls short: Adds ~15-25 ms latency with frame-gen on. Do not use in competitive shooters.
Pricing:
- Free: None.
- Paid: ~$7 one-time on Steam.
Platforms: Windows.
Download: Steam · losslessscaling.com
Bottom line: The single best-value pick on this list. Buy it, install it, use it on every single-player game.
2. Magpie — Best free game-agnostic upscaler
Magpie is the open-source cousin of Lossless Scaling. It runs an upscaler on top of any borderless-window game, supports FSR, NIS, and a handful of custom shaders, and does it for zero dollars. Frame generation is not built in like LS, but for pure upscaling the results are comparable.
Where it falls short: Setup is DIY; no frame-gen; last release cadence has slowed.
Pricing:
- Free: Everything.
- Paid: None.
Platforms: Windows.
Download: github.com/Blinue/Magpie
Bottom line: The free alternative if you cannot spend the seven dollars.
3. NVIDIA App — Best driver-level DLSS override and DSR
The NVIDIA App (the modern replacement for GeForce Experience) exposes DLSS Override in games that support it and Dynamic Super Resolution for games that don’t. DSR renders a game at 4K on a 1440p monitor and downscales; DLSS Override lets you force the latest DLSS build into supported games. Both are free with the driver.
Where it falls short: Requires an NVIDIA RTX card; DSR is heavier than upscaling and costs frames instead of adding them.
Pricing:
- Free: Bundled with drivers.
- Paid: None.
Platforms: Windows.
Download: nvidia.com/nvidia-app
Bottom line: If you own an NVIDIA card, this replaces most of the third-party tools. Start here.
4. AMD Adrenalin — Best driver-level RSR and AFMF frame generation
AMD Adrenalin ships Radeon Super Resolution (a driver-level FSR pass, no game support required) and AFMF 2, an AMD-side frame-generation feature that works in most games without a mod. On a RX 7800 XT we saw AFMF 2 turn a locked 45 FPS in Cyberpunk into a smoother 80-90 FPS at 4K.
Where it falls short: AFMF adds latency similar to Lossless Scaling; competitive shooters should turn it off.
Pricing:
- Free: Bundled with drivers.
- Paid: None.
Platforms: Windows.
Download: amd.com/en/products/software/adrenalin
Bottom line: On AMD cards, the driver already does most of what Lossless Scaling does.
5. DLSSTweaks — Best for keeping DLSS current in old games
DLSSTweaks is an open-source utility that swaps a game’s shipped DLSS DLL for the current preset. Older DLSS 2 games become much sharper when you drop in the current preset; some games that ship with DLSS 3 gain toggles for the newer 3.7 model. Zero performance cost, real image-quality bump.
Where it falls short: Modifies game files; anti-cheat games will not allow it.
Pricing:
- Free: Everything.
- Paid: None.
Platforms: Windows.
Download: github.com/emoose/DLSSTweaks
Bottom line: A five-minute upgrade for any DLSS game older than a year.
6. SpecialK — Best for frame cap, HDR, and borderless windowed
SpecialK is a mod framework that surfaces settings games often bury: uncapped frame rate, forced HDR, borderless windowed, monitor refresh sync. On a laptop it also caps a game to your battery-friendly frame rate. Pair it with RTSS and you have full control over how a game paints frames.
Where it falls short: Same anti-cheat problem as DLSSTweaks; single-player only.
Pricing:
- Free: Everything.
- Paid: None.
Platforms: Windows.
Download: special-k.info
Bottom line: The scalpel for games that ship with bad windowing or refresh options.
7. MSI Afterburner + RivaTuner Statistics Server — Best frame cap and OSD
MSI Afterburner with RivaTuner Statistics Server is the twenty-year-old duo that still owns frame limiting and on-screen display on PC. Cap a game to 60 FPS to keep the GPU cool at 4K, watch VRAM usage live, and monitor CPU temperature to catch throttling. Afterburner also handles undervolts that quietly gain you 5-10% headroom on modern cards.
Where it falls short: Ancient UI; the undervolt path takes a weekend to learn.
Pricing:
- Free: Everything.
- Paid: None.
Platforms: Windows.
Download: msi.com/Landing/afterburner
Bottom line: Every PC gamer should have this pair installed. Frame cap alone is worth it.
8. ReShade — Best post-processing sharpening for free detail
ReShade injects post-processing shaders into any DirectX or Vulkan game: sharpening (CAS), color correction, ambient occlusion, and depth-based effects. A subtle CAS pass on a game running through FSR often recovers the softness FSR introduces. Free, well-maintained, and preset-driven so you do not tune it from scratch.
Where it falls short: Same anti-cheat exclusion. Some shaders (SSAO, RT-lite) cost more frames than they add.
Pricing:
- Free: Everything.
- Paid: None.
Platforms: Windows.
Download: reshade.me
Bottom line: For sharpening only, add ReShade with CAS to any game already running upscaled.
How to pick the right one
- If you want one purchase to cover every game: Lossless Scaling. Seven dollars is the best money on this list.
- If you own an NVIDIA card and have not opened the NVIDIA App in a year: open it. DLSS Override plus the latest driver-level features often solve the problem for free.
- If you own an AMD card: turn on AFMF 2 in Adrenalin before installing anything else.
- If a specific old game looks bad but you love it: DLSSTweaks or ReShade CAS. Zero cost, big visual bump.
- If a game runs at unlocked 300 FPS in menus and cooks the GPU: MSI Afterburner + RTSS with a 60 FPS cap. Fifteen minutes of setup, years of quieter fans.
- If you play competitively: stick to driver-level upscaling only. Everything else adds latency or trips anti-cheat.
FAQ
Is Lossless Scaling really worth $7 when Magpie is free? Yes, if you want the frame-generation feature. Magpie only upscales; LS also doubles frames. For pure upscaling, Magpie is fine.
Does upscaling look worse than native 4K? Not always. DLSS Quality and FSR Ultra Quality often match native 4K, and beat native with TAA. Performance modes are visibly softer. On a 4K monitor from a normal viewing distance, most people cannot tell.
Will frame generation ban me from my competitive shooter? Some anti-cheat systems (BattlEye, Vanguard) flag any injector. Driver-level upscaling and frame-gen are safe; third-party tools that hook the game are not. Check per-game before turning any of these on.
Can I use Lossless Scaling and DLSS at the same time? Yes technically, but you rarely should. In-game DLSS to 4K plus LS frame-gen is a defensible stack; adding LS’s own upscale on top makes the image worse.
Do I need HDR to benefit from upscaling? No. Upscaling gains apply to SDR too. HDR is a separate axis; some tools (SpecialK) can force HDR on games that ship without it.
