Game looks nothing like screenshots.

[FormulaCarbon]

I tried using both VanillaPBR and Oversized, and neither gave results like the screenshot. I am using vulkanite-modified 0.0.4. What pack was used in the screenshots?

As of now my game is very bright upon loading. It gets better after but is still nowhere near the screenshots. Also, performance is much worse than it should be when utilizing vulkan.

@FormulaCarbon I tested the pack on 1.20.1, it worked well. However, on 1.20.2, you need to load a pack fit your game version like Aequalis-64x

Otherwise the normal texture and specular texture won't work or cause weird bugs like incorrect shadow.

Other game version I haven't tested yet, maybe you can tell me your game version, gpu model and screenshots

[FormulaCarbon]

i tried both 1.20.1 and 1.20.2, got same results. I have an rtx 4060 laptop gpu. will test Aequalis-64x pack and send screenshots

[FormulaCarbon]

@sjrsjz here is screenshot on latest version of Aequalis-64x

[sjrsjz]

@FormulaCarbon which branch did you use

my gpu is 4060laptop too but it has no bug

1.20.2,Aequalis-64x

[FormulaCarbon]

@sjrsjz I used whatever version of DirtRT was on modrinth. v0.1.1 I believe. I used the latest version of the texturepack. I used iris 1.6.10 and sodium 5.3.0.

[sjrsjz]

I suddenly get the following error: No known conversion to VK type for GL type RG8 (33323).

But it only appears once and i dont know why

[sjrsjz]

@FormulaCarbon I can't reproduce this error, I've tested it on three different computers with rtx 4060 but none of them have this strange problem

[FormulaCarbon]

what version iris and sodium are you using? becuase there are multiple for 1.20.1

[sjrsjz]

same as you

[FormulaCarbon]

hmm

what other mods are you using?

[sjrsjz]

No other extra mods

[FormulaCarbon]

what are your minecraft settings?

@FormulaCarbon I reproduced the bug. it could be caused by the driver version, as the error was generated after I upgraded to the latest NVIDIA driver

[FormulaCarbon]

Ah, ok. Can that be fixed in the shader or do we just need to wait for next update?

[sjrsjz]

This seems to be a nasty bug in the shader compiler, where a serious error occurs in the passing of a certain struct parameter. I have now found an alternative solution

[FormulaCarbon]

Already found a solution? That was fast.

[sjrsjz]

Maybe just passing the structure members separately would fix the problem

[FormulaCarbon]

Oh are you saying that a struct is not being interpreted properly or something?

[sjrsjz]

The data in the structure parameter seems to cause floating-point calculation errors

However there is nothing wrong with the parameters I passed in, it could only be a compiler error

[FormulaCarbon]

I’m looking at the changelog for version 551.23. First thing I see is HDR stuff and ultra-low-latency for directx12 games.

[FormulaCarbon]

I think I found it

[FormulaCarbon]

This is under vulkan-interop stuff by the way.

[FormulaCarbon]

https://us.download.nvidia.com/Windows/551.23/551.23-win11-win10-release-notes.pdf Here is link Vulkan interoperability stuff starts at 2.6

[sjrsjz]

oh thanks

[sjrsjz]

Fixed!

[FormulaCarbon]

Nice! I will try on my system when I get home.

[FormulaCarbon]

looks good but fps isnt very high. How much fps do you get and whats ur system?

[sjrsjz]

about 30fps at 720p, optimization is very bad

[sjrsjz]

This is my first real-time rendering project.
