Sr Graphics Engineer at Unity. My opinions are my own. Metal+(Vulkan&DX12). Try to keep my tweets somewhat graphics related 😊 こっちでも会話おk. ex.RL Ubisoft

Definitely interesting game to show off ue6
Having done 1k hours few years back in the game , I expect to get easily over 120 real frames, everything else is secondary. Otherwise its too hard to read how fast the ball is going and what direction far away in the field imo

UE3 vs UE6

[Juho Gävert @jugavert]

But then again I don’t own a car so who am I to speak :D

[Juho Gävert @jugavert]

Ive recently converted back from ev to gasoline for the nice engine noise. There is probably a market for that weird new ferrari, but I think in that price class… I would start looking older gasoline cars instead…
Everyday car, EV 100%

[Sebastian Aaltonen @SebAaltonen]

The new Ferrari EV looks horrible. I don't understand the urge of making EVs look like kids toy cars.

[Sebastian Aaltonen @SebAaltonen]

Now is the perfect time to write your own engine. The argument in the past was that you don't have time to write all the less important generic features. Now, the LLM will do that for you. You can focus on things that differentiate your product.

[Juho Gävert @jugavert]

Hehe, new AI model with "automatic screenshotting".
I see I see... sneaky play

[Sebastian Aaltonen @SebAaltonen]

How did the gfx industry end up like this... So many gigabytes of PSOs... So many different level of caches: RAM caches, disk caches, cloud server caches...

So much (almost) identical code repeated over and over again :(

[Gabriel Dechichi @gdechichi]

LOL turns out I was spending 15ms on memset every frame on every thread.

fixed, now ~130 FPS (still slow)

but shows how it's good to always profile first

This effect was done to replicate the look of subsurface scattering before it became technically possible (around 2002) - it was common in post to combine multiple renders and paint in extra skin shading.

I guess I had the hunch that most things are useless in DX12 and vulkan, but its nice to get confirmation!
I really like the binding api part...
Hope it won't take long until we could use API like this :)

My "No Graphics API" blog post is live! Please repost :)

After nine years of development, meshoptimizer has reached its first major version, 1.0!

This release focuses on improvements in clusterization and simplification as well as stabilization. Release announcement with more details on past, present and future is below; please RT!

[Mike Turitzin @miketuritzin]

More investigation revealed that (it appears), the creation of a DX11 context is causing the NVIDIA driver (I'm using a 4080) to put the GPU in a higher-power state, which improves perf over whatever default power state is used when just using a DX12 device.

Seen post about fps dropping from 1.67ms to 3.33ms in effect heavy combat situation.
tbh I haven't experienced it so I don't know how bad it actually feels, but!
Big fluctuations like that are bad frame pacing wise and can feel bad.
Also the 1.67ms becomes a "lie"

@SebAaltonen Now its better times with the last caretaker. https://t.co/0uyO9btYEm

New WebGPU terrain renderer build with new map and shadows!

Below: Running at stable 120Hz on ROG Ally.

Test it on your browser:

This is the reasoning why thin fan-like triangles are bad for ray-tracing on modern GPUs. Please avoid in your art.

[Sebastian Aaltonen @SebAaltonen]

Sad news. I worked at RedLynx during my early career for 12 years. Now they fire 60 people and stop making console / PC games and focus only on mobile games. Ubisoft hasn't been doing well recently, so changes like this were expected of course.

[Sebastian Aaltonen @SebAaltonen]

Our first GPU-driven renderer landed production in 2013 (XB1/PS4).

Tech artist immediately wrote a Houdini script and populated 1 million individual rocks. Draw calls were free, but lowest LOD rock = 100 triangles. I could see the future.

Today UE5 Nanite games run slowly :)
