Upscaling Explained: DLSS vs XeSS vs FSR & More

With so many options for modifying your games resolution, how do you know which upscaler to pick? Every major GPU company (Nvidia, AMD, Intel) all have different options when it comes to upscaling your gameplay. In this video Keith goes over all of the major options, including in-game scaling, NIS, RIS, FSR, DLSS, XeSS, and more.

This technology would be actually really good if you could just use them on any game.

this explained a bit to me what all these terms meant. I always found it vague but i have a better understanding now. Thank you!

I've seen a few cases where the in-game scaling is relatively good, but this especially applies to what you said that 4K output where you're working with more pixels is best. This kind of in-game scaling is very prevalent in console titles, and it's only now we are starting to see some console games use FSR (both 1.0 and 2.0) with mixed results.

I've noticed just about every newer game offers upscaling now in lieu of lowering the native resolution. This is actually a smart new standard. I decided to test upscaling compared to native when I was heavily playing Diablo 4. On my 1080ti and 4k monitor, it was pretty easy to overload with 4k native ultra settings. Heck it had trouble with 4k medium settings. The Diablo franchise came a long way in graphics, so that's nice. It can be played on super high end gear and look amazing or it can be played on grandma's hp all-in-one, still fun to play. Anyway, I found that FSR 2.0 'balanced' with all the graphics settings on ultra is the most optimal setting. The native 4k textures don't look any better than the ultra textures upscaled and the fps nearly doubles with much fewer hickups during heavy gameplay. Thanks for compiling this info to help explain all these gimmick upscaling technologies. If I had an rtx card I'd try dlss. But the AMD fsr 2 has been my go-to algorithm for many hours of Diablo 4 and it's darn good with low input latency even with the Nvidia latency reducer boost shut off

Great content it helped me a lot great work man i really appreciate ur channel and content love from India ❤

I dissagree, DLSS is absolutely in league of Its own and I noticed that it produces better image quality then native TAA, Im gaming in 1440p and Ive compared DLSS to FSR multiple times and FSR is just worse native resolution while DLSS fixes flickering and rough edges that native resolution comes with too. If you have enough performance headroom DLAA is the GOAT.

[niajef]

but what if i have nvidia card, but not RTX, so no dlss, then what should i use? FSR? TSR? or XESS?

[InternetListener]

Blocky video due to compression algorithm to adress image quality of rendering... could someone turn the quality of videos on youtube ON, please...

[jareddominguez]

He explained native res. I guess this video isnt for me....

[kotztotz]

If you are playing at 1080P, have an RTX card and want your have to look when better, you can use DLDSR in conjunction with DLSS. It basically takes a lower resolution upscales it above 1080P and then downcales it back to 1080P. You end up getting a more detailed and sharper image.
I've used it in Horizon Zero Dawn and it looks absolutely amazing IMO

[megabates]

I dislike tech videos that pretends not to be biased, whereas we all are biased.
I'd rather hear someone who assume what he likes.

[shanent]

Don't kid yourself, upscaling isn't a feature. Graphics should be drawn at a higher resolution then downscaled to the display, just like in video production where you shoot/scan at 8K and output at 2K or 4K

[bintangv]

7:05 this is what you're looking for

[Zubie]

Dear Mr. PCWorld, you made a mistake in this. A 90% scale of 1080p, which is 90% of the pixels, requires a resolution of 1821x1025. A resolution of 1728x972 only has 81% of the pixels. You can't just multiply the vertical resolution by the percentage, you have to multiply the number of pixels by the percentage (or just use an online calculator to do the math for you).

[Alpha-msnj]

Thank you for this explanation. I have a few older cards of both AMD and Nividia that I am trying out (first time PC gaming) and wanted to know what those resolution modifying methods do.
Seems like these upscaler methods can benefit older cards.

[Ludak]

And you need a solid understanding that users can't just pick which technique to use since XeSS and DLSS can only be used on their respective hardware. So If you have an AMD card, FSR is the only one you can use and you have 0 choice. With that out of the way....

I did this for the last 7 years.. I still have a cheap 4K Acer Monitor, I bought at Best Buy on sale about 7 years ago. My Old PC Rig only had an RX480 in it, so Most of the time I would set my games up at 1080P on a 4K monitor and not notice in games. But Content live movie's and thing's like that would show just how bad the monitor is.. Now I have a 6800XT and it pushes 4K all day NP.. But I am still stuck with the Acer monitor.. I want HDR badly but don't want a 27" monitor or a 42" C2 LG... it's so sad that there soooo very few Great HDR 32" monitors at or under 500 bucks.. But you can get a 42" Tv with a good 600HDR for $400/$500 Bucks it makes zero sense!! As soon as you try and find a 120Hz Tv at 32" with OLED, YOU Can't!!! they are always 60Hz at 32"s for some reason.. As soon as you hit the next size up they jump from 60hz to 120hz.. SMFH.. Why??

[lukaskubinec]

And then there is Alan Wake 2 which does not even let you play at native resolution 🥲😄 Upscaling from 540p while having RTX4080 is something abhorent in my opinion. Can you maybe make a video about what technology Remedy used since the game is beyond insanely demanding ? Upscaling from such low resolutions is huge loss for AW2 in my opinion, maybe Remedy should focus on creating better storyline than breathtaking graphics (saying that as a fan of Control)...but I digress. Thanks for the video.

Does DLSS work better on 2070 Super compared to other techs? Does it work at all?

[smveraa]

You should probably add some clarification on what technology can be used on what brand of cards, if this is geared for the "newbies".
