I know it sounds too good to be true, but there’s a $7 app that will double your performance in any game, with any graphics card. There are some caveats, as you probably suspect, but the app works shockingly well considering what it does — and I haven’t stopped using it since downloading it on Steam.

The app in question is called Lossless Scaling. It does two things. When the app released in 2018, it allowed you to upscale games (or any other content) using a more sophisticated algorithm than what your monitor uses. More recently, Lossless Scaling has added frame generation, and just a couple of weeks ago, that frame generation was overhauled.

Lossless Scaling isn’t perfect, and there’s definitely a learning curve for getting the most out of the utility. But it’s without a doubt one of the most powerful utilities installed on my PC, and it’s something I’m shocked I’ve gone so long without.

There are various forms of upscaling and frame generation available, but Lossless Scaling is special because it doesn’t care about what game you’re playing or what hardware you have installed. It works at a display level, where tools like Nvidia’s DLSS 3 and AMD’s FSR 3 work at a game level, and AMD’s Fluid Motion Frames (AFMF) works at a driver level. Lossless Scaling trades some quality with where it sits in the display chain, but it makes up for that shortcoming with support.

You can use it in any game, and that includes online games. There are various ways to inject upscaling or frame generation into games through mods, but you normally can’t use them in online games. They’ll flag the anti-cheat software, which could result in a ban. Lossless Scaling doesn’t mess with any game files, so it’s totally safe to use in an online game. I even took it out for a spin in Destiny 2 for a bit, and it worked flawlessly.

It also works with any GPU. Support for frame generation is sporadic, regardless of if you use an Nvidia or AMD GPU. Some games use FSR 3, others use DLSS 3, but most games have neither. Lossless Scaling fills in the gaps. In addition, it works with GPUs that don’t support these technologies like Intel’s Arc cards and older AMD and Nvidia graphics. Most impressive, you can run it on handhelds like the ROG Ally and Lenovo Legion Go as well.

I’m mainly focused on the frame generation here, as that’s the most impressive aspect of Lossless Scaling. Upscaling is present, however, and it works. The app includes nine different upscaling types, including Nvidia Image Sharpening (NIS) and AMD’s FidelityFX Super Resolution 1, which you can apply to any game. It works particularly well with older games that don’t support this tech, as well as emulators. That said, both Nvidia and AMD offer this same functionality through their own drivers, so you don’t need Lossless Scaling for upscaling alone.

The upscaling is also relevant outside of games. Filters like Anime4K allow you to upscale older animated content to a higher resolution and squeeze out more quality. In playing around with Lossless Scaling, that’s mainly where I found myself using the upscaling portion.

For games, however, it’s all about frame generation. Lossless Scaling works shockingly well considering what it’s capable of doing, but you need to use it properly to get the best results.

Configuration required

Lossless Scaling includes two frame generation algorithms. There’s LSFG 1.1 and LSFG 2.0, and they’re algorithms made for this app specifically that were created with machine learning. Frame generation was introduced to this app at the beginning of the year, but LSFG 2.0, which was added this month, is a massive lift in quality.

The way the app works is simple. Either you launch it through Steam, or configure it to launch at startup. Then you start playing a game. From there, you can engage the frame generation either by hitting a hotkey or by pressing the Scale button in the window. The latter option will trigger a countdown, during which you need to switch back to your game.

Your results off the bat will be bad. I considered trashing this whole article after booting up Remnant 2 with frame generation turned on. Not only was my frame rate lower with frame generation turned on, but I also encountered a mess of stuttering that made the game extremely unpleasant to play. In order to get the most out of Lossless Scaling, you need to be able to cap your frame rate in a game at a consistent spot.

I got the best results by far when I capped my frame rate to 60 frames per second (fps). Assuming I could hit that frame rate consistently in a game, Lossless Scaling would give me a near-flawless 120 fps with minimal hiccups. I stumbled upon the frame rate cap when testing Elden Ringwhich is normally capped to 60 fps. Lossless Scaling worked perfectly in that game, leading me to set a cap in other titles. The only note here is to set your cap on a per-game basis. A global frame rate cap, such as the one you can engage in the Nvidia Control Panel, will limit Lossless Scaling.

You can go lower, with 30 fps being the absolute floor, but the quality deteriorates quickly when you go below a base frame rate of 60 fps. It doesn’t need to be exactly 60 fps as long as you’re close, though. With Lossless Scaling, I went from around 50 fps in Elden Ring on the MSI Claw all the way up to 90 fpg to 100 fps.

Outside of setting a frame rate cap, you’ll also want to run in borderless full-screen mode. The app gets out of sorts when running in full screen, especially if you’re using upscaling and frame generation together. In addition, I usually like engaging Lossless Scaling with a hot key. Switching from the app back to a game can cause some issues depending on what game you’re playing.

Perhaps most important out of all of the settings in the app is the Performance mode, however. With LSFG 2.0, there’s a toggle for the Performance mode. The frame generation algorithm has quite a bit of overhead, much more than FSR 3 or DLSS 3. The Performance mode trades some quality for better performance, which is particularly useful for weaker GPUs. If you don’t use it, there are configurations that will result in lower performance with frame generation on than with it off.

Not perfect, but good enough

Lossless Scaling works very well, but it’s certainly not a full replacement for DLSS 3 or FSR 3. During fast motion, particularly in first-person games, there are artifacts. You can see that in action in Cyberpunk 2077 above. Around the tree, there’s a lot of ghosting as I quickly move back and forth. Thankfully, these aren’t too distracting in motion, and they’re certainly easy to forgive in games that don’t support DLSS 3 or FSR 3.

In addition, the app can be fickle. I’ve already mentioned the issues with full-screen modes in game, but there are certain games where you may need to quit and reopen the game before the frame generation will stick. For the most part, however, I didn’t have too many issues enabling Lossless Scaling in borderless mode with a frame rate cap enabled.

Finally, you need to have some level of stable performance feeding into Lossless Scaling for the best results. In Dragon’s Dogma 2for example, I was oscillating between a smooth experience and a choppy one depending on where I was at in the game. Ideally, you’ll want to hit 60 fps consistently with minimal drops if you want to get the most out of Lossless Scaling.

Going from a stable 60 fps to a stable 120 fps is no simple feat, though. Lossless Scaling is a bit of magic for your PC, and even on a high-end rig, I’ve been using it save power and get more consistent performance out of games. I especially like it on handhelds such as the ROG Ally, where you can get much smoother performance out of the device.

There are some issues with artifacts from time to time, and the messing around with the app isn’t always a smooth experience. I’m willing to make those compromises considering how powerful Lossless Scaling is, though. The fact that it works with any game and any GPU is a huge plus, even if you’re just filling in the gaps between FSR 3 and DLSS 3. I would recommend rolling the dice and seeing how you like the app — I could think of much worse ways to spend $7.

Console performance just took a huge step forward
Jack in Immortals of Aveum.

Choosing between PC and console just got a little trickier because a feature that was previously reserved for PCs is now available on the Xbox Series S/X and PlayStation 5. The feature in question? Frame generation, courtesy of AMD's FidelityFX Super Resolution (FSR) 3. The tech did a superb job in the first tests on Xbox Series X, resulting in an up to 72% performance uplift in Immortals of Aveum. While this is a big step for AMD, and for console gaming as a whole, there are some downsides that underscore how this tech is still in its early days on consoles.

Upon the announcement that FSR 3 was now supported on all platforms as of the latest patch in Immortals of Aveum, Digital Foundry took the game out for a spin on an Xbox Series X, sharing its experience. The game, which normally tends to run at around 30 frames per second (fps) to 60 fps on the Xbox, saw a significant increase in frame rates, moving up from an average of 46 fps to 80 fps -- a 72% increase.

I’m attending the world’s biggest PC show next week. Here’s why I’m so excited
Computex 2024 logo.

Computex will be big this year. Coming off a seismic shift in the world of PCs just a week ago with the introduction of Copilot+, Computex is the perfect place for the rest of the industry to show off what it’s been up to. This year, I’ll be on the ground in Taipei City, Taiwan, and there are some key products I expect to see.

It won’t be long before we have all the juicy details on what AMD, Intel, and Nvidia have been working on, with the show going from June 4 to June 7. There are already plenty of breadcrumbs for what we could see get announced though, so let's get into it.

Ghost of Tsushima is a great PC port with one big problem
Jin riding through a field of flowers.

After nearly four years, Ghost of Tsushima is finally available on PC. The new release includes the base game, the Legends mode, and the Iki Island expansion, as well as a suite of the latest technologies from Nvidia, AMD, and Intel. From a performance perspective, Ghost of Tsushima runs well and looks beautiful, but it has one big problem.

Sony's recent push to PC has locked players in over 170 countries out from experiencing Ghost of Tsushima, despite initially offering the game in those locations for preorder. That shouldn't distract from the excellent PC port Ghost of Tsushima is, however.
