Should You Use Upscaling for Gaming? Here‘s My Expert Take

Hey there fellow gamer! If you‘re wondering whether to use upscaling when playing games, I‘m here to help explain the pros, cons, and best practices based on my testing and expertise as an avid PC gamer. Let‘s dive in and discuss when upscaling can be beneficial, and when it‘s best avoided.

What Exactly is Upscaling?

Before we continue, let‘s quickly define what upscaling means in gaming. Upscaling refers to taking game visual assets rendered at a lower native resolution, like 1080p, and enlarging them to fit a higher resolution output, like a 1440p or 4K display.

The most basic upscaling techniques work by duplicating existing pixel color data from the lower res source to fill in the extra pixels at higher resolutions. More advanced methods like bilinear filtering interpolate colors for the new pixels to guess at smoother transitions. AI tech like Nvidia‘s DLSS analyzes source images to reconstruct even more realistic detail when upscaling.

When Can Upscaling Improve Your Gaming Experience?

Under certain circumstances, upscaling can carry some meaningful benefits:

• Allows you to display lower res sources fullscreen on higher resolution displays without ugly stretching or black bars.
• Can provide noticeable performance gains by rendering at lower native res and upscaling, reducing GPU load.
• Upscaled 1080p on a 4K screen often looks better to me than native 1080p on a 1080p monitor.

For example with my GTX 3060 Ti GPU, I‘m able to play demanding titles like Cyberpunk 2077 at over 60 FPS on my 4K monitor by running the game at 1080p and upscaling to 4K. That‘s a smooth experience I couldn‘t get with native 4K rendering on this GPU.

Potential Downsides of Upscaling You Should Know

However, upscaling can also come with some tradeoffs:

• Often introduces artifacts like blurring, jagged edges, and sharpening halos in upscaled image.
• Requires GPU resources to upscale, so it can negatively impact frame rates depending on algorithm.
• Upscaled image quality is never quite as sharp and detailed as native higher resolution rendering.

Here‘s an example comparing 1080p upscaled to 4K vs native 4K:

| Resolution | Sharpness | Aliasing | Performance |
|1080p Upscaled to 4K | Okay, slightly blurry | Some jagged edges visible | High FPS
|Native 4K | Very sharp, clean image | No noticeable aliasing | Much lower FPS

As you can see, native 4K provides the best image quality but requires more GPU power. Upscaled 4K is not as sharp but gives better FPS.

Competitive Gamers Strongly Prefer High FPS Over Resolution

Let‘s talk about competitive gaming for a moment. For esports players, achieving the highest possible framerates is absolutely critical to performance. Visual quality takes a back seat to high FPS and low input lag.

That‘s why most pro players run their games at 1080p low settings to maximize framerates, even on higher resolution monitors. Upscaling would only add input lag, so competitive gamers avoid it in favor of raw performance.

Upscaling as an Option for More Casual Play

For more casual single player or story-driven games, upscaling from 1080p to 1440p or 4K can provide a great blend of visual quality and performance, depending on your GPU. The improved image over native 1080p can make for a more immersive experience.

I‘ll often use DLSS Frame Generation to upscale from 1440p to 4K when playing cinematic games like Cyberpunk on my RTX 3080. This lets me enjoy over 100 FPS at near-4K image quality with DLSS handling the upscaling well.

My Recommendations for Using Upscaling

Based on my testing and experience, here are my recommendations on when upscaling can make sense and when to avoid it:

• Target your monitor‘s native res if possible for sharpest image. But upscaling well-optimized 1080p to 4K can work great too.
• Upscaling algorithms make a big difference – DLSS and FSR are much better than basic bilinear filtering.
• Evaluate FPS vs visual quality tradeoff yourself. Upscaling sometimes impacts FPS counterintuitively.
• Avoid upscaling for competitive multiplayer – go native 1080p or 1440p for high FPS.
• Consider upscaling for cinematic single player games if you have a capable GPU.

I suggest trying native rendering and upscaled modes yourself to see which provides the best balance for your games, system, and preference. Do some benchmarking, analyze the numbers, and enjoy finding your optimal settings! Let me know if you have any other questions.
