Jusant is a new action-puzzle climbing game that uses Unreal Engine 5 and takes advantage of both Lumen and Nanite. And, unlike Fort Solis and Immortals of Aveum, Jusant appears to be running smoothly on PC. Thus, we’ve decided to share a Native 8K/Max Settings video of Jusant running on an RTX 4090, as well as our initial performance impressions of it.
In order to capture this video, we used an AMD Ryzen 9 7950X3D, 32GB of DDR5 at 6000Mhz, and NVIDIA’s RTX 4090. We also used Windows 10 64-bit and the GeForce 536.99 driver. Furthermore, we’ve disabled the second CCD on our 7950X3D.
As DON’T NOD noted, this preview build is not representative of the performance of the final game. However, and contrary to other UE5 games, Jusant already runs great. So that’s at least good news for those interested in this title.
Strangely enough, the game does not support Intel Xess, NVIDIA DLSS 2 or DLSS 3. Instead, the only available upscaling technique is AMD’s FSR 2.0. Let’s hope that the final version will support DLSS 2 and XeSS.
At Native 4K/Max Settings, our NVIDIA RTX 4090 was able to provide a smooth gaming experience. During our benchmark sequence, there was only one scene in which our framerate dropped to 58fps. For the rest of the test, our RTX 4090 was able to provide framerates higher than 60fps. As for Native 8K/Max Settings, the RTX 4090 can push framerates between 24fps and 30fps.
As said, the good news is that Jusant takes advantage of both Lumen and Nanite. Thus, there aren’t any geometry or object pop-ins. Now while its scope is smaller than Immortals of Aveum or Fort Solis, Jusant clearly shows that developers can use these features without completely destroying a game’s performance.
Jusant will officially release on October 31st.
Enjoy this 8K video for Jusant and stay tuned for more!

John still clinging on to his RTX4090 eventhough it’s hopelessly outdated for these UE5 games.
How would you know what outdated means? You can’t even read numbers.

That screenshot makes you look like the idiot. https://uploads.disquscdn.com/images/11791266a1f8b08e2a500e00c4225118226796fe916856097838b9056c52ccc9.png
I assume this is some cultural difference between how money is represented?
Another illiterate.
Do you write math from right to left in your sh*t country?
Jesus christ you dumbass, I was defending you/giving you an out and saying the screenshot you used made you look like an idiot (it’s missing context). FFS.
Giving me an out? lmao
probably, it’s a difference in decimal notation
1.000 = one thousand in Europe, South America and Africa
1.000 = one in the US, UK, Australia, China

Dagoat probably doesn’t know about the difference in decimal notation.
1.000 = one thousand
(Europe, South America and Africa)
1.000 = one

Plenty of stories of US tourists who think they are getting off cheap in a foreign country, until they get home and look at their credit card bill.

Game gives ICO vibes. But the whole video was the dude doing nothing but climbing which makes me think the game will lack any creative gameplay
i think from demo only real issue imo is lack of failstate, but its still nice if just want some more relaxing experience. its no ico.
Another western walking sim pretending to be a game, and then after the game launch there will be accompanied article from ‘journalist’ how this game reflect our society deep inside, how it mirror loneliness they felt, how it represented their being in this world, etc, bla bla bla…
C’mon its just a game, if its suck said it is suck , boring etc, didnt need to excuse just to play the game and make it more than it is
Motion > resolution/graphical fidelity
The video tied to this article was not pleasant to watch
wtf is this abomination. I bet it was designed by troons or token femoids.
This game looks like they could’ve made it in UE4 and easily doubled the performance by baking in the lights instead of relying on UE5’s Lumen. “Bububut muh real time globull illumeenayshuns!” Who TF cares, this is an indie-slop title with simplistic graphics, not some AAA open world game with a dynamic time of day system that actually affects gameplay in any manner. What an utter waste of resources.
Baking lighting requires A LOT of work. The only ones that can get away with baking lighting are triple-A studios with a lot of people. It wouldn’t be possible for a small team to create and ship this game in such a short time.
Yes it would. Don’t Nod are the same people who made Remember Me about a decade ago, which was using Unreal Engine 3 and had great looking baked lighting all over the place. The render time to bake-in lighting has reduced drastically since then thanks to the large advancements in computer hardware. Heck, they now have the hardware to preview their lighting in real-time prior to baking it in so the time to iterate and refine the lighting would also be greatly reduced. There’s really no excuse.
I might be wrong, but can’t you bake the lighting by using ray tracing and then mapping that? without requiring that much work?
I know what does require a lot of work are dynamic lighting systems which are probe based.
I mean, ray tracing used offline, then shipping the results.
Could have made it in UE3, and then it would have run on a toaster and probably looked about the same…
Agree, its just a waste of GPU Power with very miniscule return in graphical fidelity compared to bake lighting. Im hoping to be blown away because its UE5 but when playing the demo its just remind me of the game called Rime for half decade ago but heavier (it reach more than 60 at first but degrade performance further we go with my RTX 3060 Ti)
I also have a 3060 Ti so I know exactly what you’re talking about. There were instances in the demo where the FPS dipped down to mid 40s while being INDOORS. And this was at 1080p. The absolute state of modern day game optimization…
So after the Immortals of blabla debacle, John kept searching for some sh*t UE5 game that can run at more than 35 fps on his 1500$ GPU so he can keep defending that engine… This game is so low-poly that it could run without a PC in a normal world, the desk alone can run it, but since it’s UE5 you’re happily enjoying a basic 60 fps with a smile… I don’t even know what word i should use to qualifie this situation, “pathetic” is not enough
The RTX 4090 is a $1600+ GPU.
Yeah, there’s a bunch of AIB partner RTX 4090’s that are over $2000. I just checked the prices, and most of the ones on Amazon are over $2000 (NewEgg and BestBuy were short on stock but what they had was less expensive).
Its $2500 + Tax + Whatever distributor wanted to charged here

Dark side of gaming or else dark side of Unreal or dark side of nvidia.
Where 8K gaming monitors? Why don’t we have 8K 144Hz displays?
really? when I tried the demo the performance was below par…
Yep, the performance degrade further the longer we play, at least that what I got with my 3060 Ti
