Shaders looks different (bug) on two different computers.

Hello! :)

So, I picked up The Human Gallery after a long break, approx. 5 months!
Back then I simply had too many problems, and I reported these to bug tracker. CT has fixed these (maintaining screen aspect ratio, shader related crash when using textures), anyways, I was excited to get back developing as everything seemed to work great! :)

I thought I'll give tech demo a go on my wife's laptop (It's quite decent one actually, GPU GTX 960m) and to my surprise I noticed that the game looks all funny, especially the intro. Also in game I noticed a few lighter, gray boxes on the screen. Well, it was obvious that shaders where causing the problems somehow!
To mention, I run executable by right clicking the executable and select to use nvidia gpu, the integrated won't quite do it! So the problem isn't that I would accidentally use the integrated graphics. I use Nvidia gpu and the game runs smoothly 60fps. :)

I'm using quite a few shaders: Screen, Color Dodge, Normal Map, Blur, Substract etc. I started deleting shaders from the intro and I noticed blur shader had the biggest impact, though there are still some graphical bugs and errors. It's obvious that something is malfunctioning.

Does anyone know what could be the cause? Is there anything shaders would need in order to work properly?
I believe I've direct X installed as I've played some games with the laptop, like Alien Isolation.

All the ideas and suggestions would be welcome!

EDIT: Fixed the GPU, was wrong before. :)

EDIT2: Did a small discovery, I ran the game with integrated graphics, and all the shaders appeared correctly! The game is slow as heck though. Anyways, I believe it might be GPU related.

Thanks,

Jesse

This is interesting (and scary :o)
as many could experience same issues without knowing how to change GPU settings,
so maybe this is something one should think at?

On the slowness -
I would be interested hearing other reports on Win10 + shaders
if there's any difference in the way DirectX libraries are applied,
just to make sure this is not related to any incompatibility with the new Win OS

Did you update your desktop pc to Win10 too?
All runs fine there?

Hey schrodinger! :)

Indeed, I have 64 bit Windows 10, and so does the laptop, systems are pretty similar. It works just fine on my rig! :)

My desktop has Gtx 780 which is direct 11, and the laptop Gtx 960m which is direct 12. This is pretty much the only difference I can tell. I'll try to look if I need to install some libraries in order to make it work.
I really don't understand much about the technical stuff, like processing of the GPUs so the difference can be there too.

I will try tweaking settings one by one from the nvidia control panel, and see if I can find a settings that makes difference.

Thanks for the reply man! :)

mmmmmm I have a fear there's something odd with DirectX12
I even see some people online reverting to previous versions
(Win10 most recent versions seems to come bundled with DirectX12 ?)

Will try myself next days as I have a laptop to upgrade on Win10.

...OR maybe graphic cards drivers need to be updated to support DX12?

Anyone interested, to check your directX version,
hold win key + R (run)
and type "dxdiag" - OK
At the bottom of "System" tab you'll see your DirectX version.

Very interested in feedback from Win10/DirectX12 users!

Thank you Jesse for making us aware oof this issue, could be worth a broad check :)

It might be related to that, but I feel there's more to it. I'm even doubting my code, though if it works here, then I don't see how it wouldn't work on the laptop.

I think I've seen this problem before with Silence of the Sleep. I noticed some of the let's players had similar box on the screen, that made the some of the area a bit more bright. Thought with SotS it's possible my code did that hah. :D
Also I think one of the players reported weird graphical artifacts in chapter two (SotS), so it's possible it's related.

Any info or similar experiences would be more than welcome!

Oh, and I couldn't get around the problem by trying different settings from the Nvidia panel.

You're welcome schrodinger. XD

Hey, interesting post.

I'm working on a DOom style game in Shrodingers P3D engine.

I've had huge performance issue with a new laptop, running GTX960m Direct X 12.

Old (basically identical) Win7 laptop with Direct X 11 runs the game fine.

New laptop with DX12 crawls horrible on integrated graphics. Runs a clean 60 with GTX960, but has tearing/abberations/missing assets.

So looks like it could be more an issue with the GTX960&DX12 than DX12 over all!

Yeah, starting to seem like there's something wonky with either Direct X 12, or with most computer's drivers not working nicely with Direct X 12...

Whatever the reason is, we really need to figure it out. Though if it was only 960m and dx12, then how come pretty much all the other games works without a problem?
More and more people are buying new cards, so this is potentially a very scary problem, does Clickteam have any idea what could be causing this? :)

ehm, bump >:)

maybe we should post this in the bugbox?

Anyone else having problems with DirectX 12 and shaders in Fusion?

Or anyone not having issues with DirectX 12 and shaders in Fusion? XD

(btw, I wonder if Fusion2.5 will ever support most recent DirectX versions, maybe only Fusion3 will?
Could allow for a different generation of shaders, and maybe better performances too)

I have Win 10 on my Surface Pro 3 and can confirm that the shaders I have used appear as normal on it. It's mostly Add blending. But I don't know if it has DX12. I'm under the assumption Win 10 comes with DX12 in installation?
