When a game runs too slowly and you have already turned down settings, upscaling is the next lever — and NVIDIA Image Scaling, or NIS, is the most broadly compatible option. Unlike some upscalers that require specific game support, NIS works at the driver level in virtually any game by rendering at a lower resolution and intelligently sharpening the upscaled image. It is a quick way to reclaim frames on older cards or in titles that lack fancier upscaling, and it costs nothing to enable.
How NIS works
NIS renders the game internally at a resolution below your monitor’s native, then upscales it to fill the screen and applies a sharpening pass to recover apparent detail. Because the GPU pushes fewer pixels, frame rate climbs. The sharpening keeps the result looking crisper than a plain stretched image, though it is a spatial technique and does not reconstruct detail the way more advanced, game-integrated upscalers do.
Enable NIS in the control panel
Open the NVIDIA Control Panel, go to Manage 3D Settings, and turn on Image Scaling, choosing a sharpness value to start — around 50 percent is a sensible default. Enabling it exposes a set of scaled resolutions. You then select one of those lower resolutions inside the game, and the driver upscales it back to your native panel resolution.
| Render scale | Internal res (for 1440p) | Rough FPS gain |
|---|---|---|
| 85% | ~2176×1224 | Small, near-native look |
| 77% | ~1970×1108 | Moderate |
| 67% | ~1706×960 | Large, softer image |
Pick the right render resolution
The lower the internal resolution, the more frames you gain and the softer the image becomes. A gentle scale keeps the picture close to native while still helping performance; an aggressive scale delivers a big frame-rate jump at the cost of some clarity. Start gentle and only drop further if you still need frames.
Tuning sharpness
The sharpening slider strongly affects the final look. Too little and the upscaled image looks soft; too much and edges get a harsh, over-sharpened halo. Find a middle value where the image looks crisp but natural. Because taste and content vary, spend a minute adjusting it in an actual game scene rather than trusting a single number.
When to choose a different upscaler
If a game supports a modern temporal upscaler built for that title, that will usually look better than NIS at the same performance level because it reconstructs detail across frames. NIS earns its place when a game lacks those options, on older hardware, or when you want a simple driver-level solution that works everywhere without per-game support.
Frequently asked questions
Does NIS work in every game?
Practically, yes — because it operates at the driver level, it works in almost any game where you can select the scaled resolution it creates. That universality is its main advantage over upscalers that need to be built into each specific game.
Will NIS make my games look blurry?
A little softness is the trade-off for the frame-rate gain, and it grows as you lower the internal resolution. The sharpening pass counteracts much of it, so a gentle scale with tuned sharpness stays close to native. If clarity matters most, use a light render scale rather than an aggressive one.
Where NIS fits in your performance toolkit
Think of NIS as one option among several for reclaiming frames, best deployed when others are unavailable. If a game already offers a modern temporal upscaler, start there for superior image quality at the same performance. When it does not, NIS steps in with its universal, driver-level approach. It also stacks conceptually with the usual settings work: lowering a couple of the heaviest options like shadows and volumetrics, capping your frame rate for consistency, and keeping drivers current all contribute alongside the resolution scaling. On older cards especially, a gentle NIS render scale can be the difference between a stuttery experience and a comfortably smooth one, extending the useful life of hardware by a generation. Because it is a spatial technique, fast motion and fine detail suffer more than with temporal methods, so reserve aggressive scaling for when you genuinely need the frames. Used judiciously, NIS is a dependable tool that works absolutely everywhere.
Bottom line
NVIDIA Image Scaling is a universal, driver-level way to trade a little sharpness for more frames in nearly any game. Enable it in the control panel, pick a scaled resolution in-game, and tune the sharpness to taste. It is not as clean as game-integrated temporal upscalers, but when those are unavailable, NIS is the reliable fallback that keeps older cards and demanding titles playable.
