Texture streaming issue

4 GB vram? that’s a nice constraint. that 1.6 GB engine footprint looks pretty good tho. stylized looks good too. maybe you should try to lower the streaming pool and force the engine to run the graphics entirely from GPU memory, not managed. the streaming pooling is a balance act between RAM cache and actual memory on the GPU. if you have 2 GB of GPU texture memory free and the textures you use fit in there, you may not need to stream alot, just a bare minimum to keep the graphics running wihout reloading hitches.

well i have a question, may this issue only happen on my pc or it will happen on other different devices since its the engine and not the pc?

if you squeeze the graphics/textures into 4 gb of video memory it will run fine for anybody with 4 gb. it will use lower resolution textures on less capable devices and will look just like yours on more then that.

Not that I’m aware of.

I’ve been working with some people in the forum to figure this out.

An example:

I set my pool at 800MB. Unreal, at times, says I’m 6GB over budget, but the TASK MANAGER shows I’m only using around 40% of my 8GB of memory.

This started happening around the most recent NVIDIA update. So, I imagine the issue is linked, and may not be resolved, officially, for some time.

Resetting the pool size will work, but Unreal will still bottleneck the texture streaming.

Ugh, what a mess.

well as it seems there is no TRUE solution to this, so i guess for the mean time texture streaming will be off, till hopefully some NIVIDIA update happens, and also talking about NIVIDA drivers, when i use unreal for like 30 mins or more, the tabs will start glitching and will turn black or transparent, but if i move the tab to the other screen which uses the intel graphics its fine, and i’ve seen some solutions for this is to turn your graphic drivers into what i think is called design type and not gaming, but it doesnt really seem like a solution but it just seems all the visual issues happen from NIVIDA side and not unreal.

Windows Key + Control + Shift + B = reset your graphics drivers

I’ve submitted this bug report to Unreal and Nvidia, and suggested to others who have the same issue to do the same. I hope you will as well, as to expedite an actual fix to the issue.

ALSO

I tested packaged versions and they WORK. The texture streaming is completely normal in a packaged game.

yeah i will also make sure to report the bug,

good to know the texture streaming works on a packaged game, for me it was weird sometimes it would work sometimes it wont.
