As in Issue https://github.com/Dysoch/DyTech/issues/308

When DyTech Machine 1.0.3 and DyTech-Core 1.1.3 are installed, the Game can't be resize to 4k (3840x2160 pixels). When this is done, the Game Crash with the error
Unable to create sprite (3836X2066) probably not enough of video memory.
PC Specs, to confirm that the PC Specs are not the real problem here.

Amount of VRAM is not present in the log as far as I can see - I'd recommend lowering graphical details and retrying.
I think that DyTech Machine mod has quite a lot of graphical assets.

On the other hand standard memory for this GPU should be 4GB... that would mean something strange is going on. Are you running on latest drivers?
One message from log thats a bit strange is the failed attempt to make 16k texture - it should work on that class of GPU I think.

Posted: **Tue Jun 09, 2015 3:53 pm**

I'm running always on the latest driver to have not this kinds of problems

And i Think to that this is strange because that means that the things the Game put in the VRAM is 4 times of the Game itself, if not more!

The way graphics work, that isn't hard to believe. Do graphics cards have a hardware PNG decoding system, to render them stright on your screen in a single, simple, fast process? I highly doubt it, therefore all image files would need to be decompressed into Bitmap images before they can be used (which would inflate their filesize to 4 times, or more)

on top of that, the game will draw the screen in layers. you'll need 3840x2160x4 bytes of memory just for the screen overlay, on top of that, all the graphics for the game. if you have less than a half gig in your graphics card, the game would find it hard to run, with a 4K screen, I'd recomend a 1GB graphics card, MINIMUM, probably more like a 2GB card. Larger resolution screens are really memory hungry.

I Added the PC Specs and the Console Log to clarify some things

Can you download GPU-Z and check amount of memory for GPU?
With 4GB it should work.. with 2GB might be a problem at that kind of resolution (it's about 4 times full hd).
You can try to change graphics quality to lower before resizing game to full screen.

You never heard about the nVidea fail with the GTX 970, haven't you?

So in short:
The GTX970 has 4GB VRAM where only 3,5GB are fast, and the other 0,5GB are slow.

There is a non zero chance you have .. to much of VRAM?

More pepole with 4k display would be useful to test if game works for them without problems.

This bug seems to fit into the 1/0 magic category.

Posted: **Tue Jun 09, 2015 10:19 pm**

Does it work in 3840x2160 if you disable Dytech?

Does Dytech work if you use lower resolution?

Yes and Yes.

I Run it in Window Mode and if i don't resize the Window to make it bigger, it won't crash.

"Vanilla" Factorio runs perfectly fine with highest Framerates on 4k.

Someone could also test this with http://en.wikipedia.org/wiki/Supersampling

Posted: **Tue Jun 16, 2015 1:19 pm**

as im seeing it know, it was moved to 1/0 magic ?

That means it will never been fixed because no one try it with supersampling an 3840x2160 resolution?

I mean: it could be a wrong error message or a wrong image handling.

But ok, nevermind. I think i can't play any mods now.

Posted: **Tue Jun 16, 2015 3:49 pm**

Well, there is nothing I can do about it as long as I can't reproduce it.

And even if I could reproduce it I'm not really sure I would be able to find out what is causing the problem, when the graphics card just refuses to create the bitmap.

Posted: **Wed Jun 17, 2015 8:27 am**

so the error won't occure when super-sampling in 4k resolution is used?
Then i understand that, but currently couldn'T any GTX 970 User play Factorio with mods, if im right

But ok, i will wait till something happend, till then: no mods

Posted: **Wed Jun 17, 2015 12:54 pm**

It depends how many mods you use and how much memory requirements do they have. It could be, that you simply ran out of the video memory.

If you upload the mods folder I can try to reproduce it.

Btw, we found out, that there is an error in the graphics library we use. It stores the copy of the bitmaps in RAM once instead of twice, so the RAM requirements will be much less after this update. It is not probably the cause of the problem, but it could.

This will actually probably solve the problem. I just noticed Serverfrog is running 32bit Windows 8 (or 32bit build of Factorio), so he is probably actually running out of RAM, since he has available only 2GB per process.

Serverfrog: if you have 64-bit Windows, download 64-bit build of Factorio.
