The first Jellyfin setting I enable gives me a feature that Plex puts behind a paywall


Transcoding is an unavoidable part of both the Plex and Jellyfin experiences. When it’s required, converting your videos in real time into a format that your client devices can handle is slow and resource-heavy and is the main cause of buffering and stuttering. But you can speed it up significantly by enabling hardware acceleration on both platforms. The big difference is that on Plex, you have to pay for it. On Jellyfin, it’s free.

What hardware acceleration is and why it matters

Eliminate buffering in a single stroke

Hardware acceleration can deliver much smoother and more reliable performance in Jellyfin. To understand how, it’s worth recapping how your media server plays videos.

Your Jellyfin server can handle nearly all common video formats and codecs. But that doesn’t mean it can play them all quite so easily. Whether a video can play directly depends on the capabilities of the device you’re watching it on. What plays natively on a modern iPad, for instance, might need transcoding on a smart TV or an old Fire Stick. And if you (or your other users) have multiple different devices on your network, your experience can vary massively.

Direct play in Jellyfin.

Files that are supported use Direct Play, and the original file streams completely untouched. When you try to play a file that your hardware can’t handle for any reason, the Jellyfin server converts — or transcodes — it to a format that your device does support. It has to do it in real time (since you’re trying to watch it), and it is a very processor-intensive task.

The transcoding note in Jellyfin.

By default, Jellyfin uses software transcoding via the CPU. It consumes a significant amount of processing power and can result in buffering. It limits how many simultaneous streams your server can handle and has a knock-on effect on other server tasks, causing Jellyfin to be generally slower and less responsive.

When you enable hardware acceleration, Jellyfin offloads the transcoding to your GPU. By using a piece of hardware that’s optimized for media decoding and encoding, it delivers much better and more efficient real-time performance. The video will start playing more quickly, even with multiple users on the system, and you’ll see less stuttering and buffering. Even a simple thing like scrubbing through a video becomes more responsive.

I keep hardware acceleration enabled on my Mac-based Jellyfin server, and it cuts the CPU usage for a single transcode from around 90% to a fraction of that. It’s one of the big selling points of Jellyfin compared to Plex, because while the latter does also offer it, you need an increasingly pricey Plex Pass subscription to use it.

How to enable hardware acceleration in Jellyfin

Toggle on the setting

Hardware acceleration is switched off by default in Jellyfin. Support is dependent on your hardware setup, which can bring potential compatibility and stability issues on some systems. Jellyfin supports several GPUs, including Intel, NVIDIA, AMD, and Apple.

To find the setting, open the Dashboard on your Jellyfin server and go to Playback > Transcoding. Click the Hardware Acceleration dropdown and select your hardware from the list.

This will reveal some additional settings that are specific to your GPU. I recommend checking the official documentation, which leads you through the setup for each option. This includes downloading the drivers you need on some operating systems and some recommended settings. For the most part, it’s as simple as enabling the setting on Windows and Mac, with Linux and Docker installations requiring more hands-on configuration.

The main settings you need to enable are for Decoding, to process the source video, and Encoding, to create the converted stream for the client device. Using both provides the biggest cut in CPU usage. There are also settings that let you choose a balance between speed and quality in the encoding, and you might want to enable tone mapping if you have a lot of 4K HDR files, as they’re the most demanding to transcode.

It’s important to remember that not every GPU supports every codec. Where you have a video that isn’t supported, the system will fall back to software transcoding instead. Longer term, it might be worth using an app like HandBrake to convert files that your hardware doesn’t support. Some GPUs also limit how many files can be transcoded at the same time.

CPU load on a Mac with and without hardware acceleration.

But it’s likely that many of your files will be supported, and the benefits will become immediately obvious. Using the Activity Monitor tool on my Mac, there is a clear difference in CPU load depending on whether I’m using software transcoding or hardware-accelerated transcoding.

Free hardware acceleration is a key reason to choose Jellyfin over Plex

It’s a game-changing improvement

To be clear, Direct Play is still the preferred way to go for buffer-free streaming. Encoding your video files with codecs and in formats that your client devices can play without transcoding will deliver the smoothest and most stable performance of all.

But this takes some planning, and if you’ve got a large library, it simply won’t be viable to convert everything. When you do have to fall back on transcoding, hardware acceleration is a game-changer. It significantly cuts the load on the CPU, uses less power, and provides a better user experience for both you and everyone else who shares your library.

And the fact that it is free makes it one of the most compelling reasons to choose Jellyfin over Plex. It’s not that Plex lacks hardware acceleration; it has excellent support for it. But it treats it as a premium feature rather than something that’s available to everyone. Getting one of the biggest performance upgrades for free is hard to beat.

I’ve driven a lot of EVs lately, and many of them seem obsessed with feeling futuristic at all costs. Some are great tech showcases, but not all of them are particularly easy to live with day to day.

The 2026 Polestar 3 Dual Motor Performance is different because it doesn’t lean into that over-the-top EV personality. It feels like a proper luxury SUV first, and an electric vehicle second.

With 680 horsepower on tap, it’s seriously quick when you want it to be. But the real story is how normal it feels when you’re just going about daily driving.

Pros

Cons

  • Feels more like a normal luxury SUV than a typical EV
  • Strong performance
  • Excellent interior quality
  • Firm ride
  • Smaller cargo space than rivals
  • Expensive options that put the price up quickly

A luxury SUV first, an EV second

It behaves more like a traditional premium SUV than a futuristic EV

The first thing you notice about the 2026 Polestar 3 is how little it tries to act like a typical EV. It doesn’t lean on gimmicks or exaggerated futuristic styling cues.

Instead, it feels like a well-sorted luxury SUV that just happens to be electric. That approach instantly separates it from much of the competition.

The steering feels natural, and the ride is controlled without feeling overly soft or disconnected. It avoids the detached “floating tech pod” sensation that some EVs still struggle with.

Even in Performance trim, it never feels dramatic for the sake of it. Everything is tuned around calmness and everyday usability.

You sit lower in the Polestar 3 than you might expect for a large SUV. That gives it a slightly cocooned driving position that feels more focused than most rivals.

At first, it almost feels like you’re in something smaller and more sports-oriented. That illusion works especially well in everyday driving.

But the reality check comes when you push harder. The weight shows up under braking and reminds you what this really is.

The cabin follows a minimalist Scandinavian design approach that feels calm rather than cold. It avoids the overly futuristic interiors common in many EVs.

Most functions are handled through a large central touchscreen running Google’s system. It looks excellent, but it takes time to get used to.

Core controls like drive settings and climate adjustments aren’t instantly accessible. It keeps the cabin visually clean but less immediate in use.

There are also quirks like relocated rear window switches and unlabeled steering wheel buttons. They don’t ruin the experience, but they do take time to learn.

Rear seat space is one of the Polestar 3’s strongest points. The five-seat layout allows generous legroom throughout.

Even taller passengers won’t struggle for space in the back. Headroom is slightly limited by the sloping roofline, but it doesn’t feel restrictive.

Cargo space is average for the class, with a shallow load floor and raised cargo area. You also get underfloor storage plus a small frunk for charging cables and small items.

A panoramic glass roof comes as standard and makes the cabin feel noticeably more open. It helps offset darker interior themes.

The design is restrained but not sterile, which suits the character of the car well. It feels more like a calm living space than a tech showcase.

Ambient lighting adds subtle personality without becoming distracting. It reinforces the relaxed, everyday usability of the cabin.

Polestar has removed most physical controls in favor of a screen-first interior. That keeps the design clean but increases the learning curve.

The 14.5-inch display looks sharp and responds quickly, but key functions often take more steps than expected. Even simple adjustments aren’t always immediate.

It reinforces the modern EV feel, but it also highlights the tradeoff. This is where the “normal SUV feel” starts to give way to full EV complexity.

The Polestar 3 had a difficult start to life, with delays and early software issues affecting its rollout. This update feels like the version it should have launched as.

The biggest change is the switch to an 800-volt electrical architecture. That brings much faster charging speeds and shorter stops on compatible fast chargers.

All versions also get new batteries and updated in-house motors. The lineup has been simplified into three clearer variants based on powertrain.

The Dual Motor Performance model now produces 680 horsepower. Despite that, it still feels more like a relaxed luxury SUV than a performance machine most of the time.

The 2026 Polestar 3 starts at £71,540 ($91,000), rising to £79,540 ($101,000) for the Dual Motor and £87,040 ($111,000) for the Performance. That puts it firmly against the BMW iX and Mercedes EQE SUV rather than mainstream electric SUVs.

Standard equipment is strong across the range, with 20-inch alloy wheels, a 14.5-inch portrait touchscreen, a Bowers & Wilkins sound system, and a full suite of driver assistance tech. It feels well-equipped even before options enter the conversation.

Move up to the Dual Motor and you get dual-chamber air suspension and subtle Swedish gold detailing. The Performance model adds significant power, revised chassis tuning, gold Brembo brake calipers, and gold seatbelts.

Where costs rise is options. Paint starts at £1,000 ($1,270), while Bridge of Weir leather upholstery costs around £3,900 ($4,950).

Even so, it feels more complete out of the box than many rivals in this segment. The base price is high, but it doesn’t feel stripped back or artificially entry-level.

How-To Geek’s take

An EV that finally behaves like a normal car first

The updated Polestar 3 doesn’t try to reinvent what an electric SUV should be. Instead, it focuses on feeling familiar, calm, and easy to live with.

It still has compromises, including a firm ride and heavy touchscreen reliance. But it avoids the overly futuristic feel that turns some drivers away from EVs entirely.

That’s what makes it work. It feels like an electric SUV for people who don’t usually like electric SUVs, and it commits to that idea from start to finish.
