one other issue i mentioned above is when you get that texture streaming error where its red and need to increase teh pool BE VERY careful as it will give this error too i have 6GB card with 1.9 gb shared and i have no errors now at 2000 poolsize hit tilde r.Streaming.PoolSize 1 ( run your project and see how under it is and go a few hundred more like if its avging 1500 set to 1800 or 2000 ) to do that r.Streaming.PoolSize 2000 be warned this is for my 1660 super and if youhave less vram your going to have to do things like in settings and scale back to low and keep the pool less only other option then becomes MORE vram

After enabling virtual texturing and then selecting the 'enable texture streaming' option, my render has finally started and I'm able to render on HD with only 4gb vram. You've singlehandedly saved my project (For anyone having similar problems; I have a GTX1650 maxQ, 8gb RAM of which 4 is vram)

It's hard to troubleshoot issues via youtube comments, but I would suggest toning down the ScreenPercentage just to get an idea and narrowing down the source of the problem. If turning it down helps, then you know your scene maybe a bit too heavy. If lowering screenpercentage DOESN'T help, then you have something in your scene causing it to crash, from there it's a matter of removing certain aspects of the scene one by one until you get a successful render, and moving forward from there. Render wrangling is an artform of its own!

Great vid! :) Learning optimization techniques can save a lot of time and nerves for almost any UE user. I'm using an old gear, GTX960 4GB, Phenom II x955 and 8GB ram and I can't recall when my last crash was (expect when I tried to import metahuman ^^). Trick is to optimize all of your assets, even those from marketplace or megascans (channel packing, for example, is not set up by default), since they are often designed to look as good as possible for marketing reasons, so their materials are just too expensive for many uses. 4k textures - only when they are really needed, so in my case - almost never. For highest quality cinematics only: sure, a lot of Vram is definitely required, but as for now, you definitely can make beautiful games with an old rig like mine without big troubles, so to anyone demotivated - don't give up! :)

Also a big help has been putting high memory usage assets like characters/crowds into a visibility layer that I toggle on\off in the sequencer as well as for during editing. This reduced the frequency of UE4 crashing a lot. Even with using a 3090 my UE4 still crashes.

So from what I've heard, DLSS doesn't work with the Movie Render Queue, unfortunately. Have you considered trying to change your TDR value? By default TDR is set to a short value of about 2 seconds, if a GPU process takes longer than that, it can reset the graphics driver and cause a crash. you can read about it here. It's a document for substance painter, but the same applies to Unreal: docs.substance3d.com/spdoc/gpu-drivers-crash-with-long-computations-128745489.html

I just found out today about the gpu visualizer for a specific frame, hotkey is ctrl+shift+, you can dig down into whats causing a still image to be having lag, I was at around 80ms with 4k textures and raytracing enabled and turning volumetric fog for the exponential height fog off helped a fair share. Disable RTX when unsure alltogether.

There are a few other obscure tips floating around, what did it for me was simply going into the nvidia control panel and limitting Unreal to 30fps. No crashes since. Mind you, crashes have been waaay less frequent with unreal 4.26 and even Unreal 5.0EA. The switch to shadermodel 6 as a requirement seems to have caused a bunch of issues.

Hm? Strange... i tried unreal engine 4.25 and didn’t came across this problem while in 4.26 with dx12 I having this issue. The older one doesn’t have the inbuilt gpu lightmass and takes longer since I need to use the older method of getting gpu lightmass. I have a 1160 super that supports dxr.

According to Epic, in 4.26, you need to enable Raytracing for GPU lightmass to work: docs.unrealengine.com/en-US/RenderingAndGraphics/GPULightmass/index.html

@@WilliamFaucher yes i know. i think there is a bug in the dx12 rhi setting. in version 4.25 with both raytracing & dx12 rhi enabled i could render a whole game level without any problem. the only problem with the older version is that you need to download a gpu light mass plugin manually and install it manually.

Hey Will, first of all, thanks for taking the time to help people out. I have a 3080TI with a Ryzen 7 3700X and 750W PSU (which might be problem, but before I spend a couple of hundred $ I thought I'd see if you have any insight). My issue seems to be with UE4 games with the D3D device removed crash message.. Rocket League (UE3) does not crash. Drivers are up to date. I looked into the TDR Delay, but that doesn't exist in my registry? Unreal Engine is updated to 4.21.2 currently and Windows is updated. The first crash happened after a 3.5 hour stream of Satisfactory (which runs on UE4) and now, it won't stay opened for more than 5mins. Any thoughts?

@@WilliamFaucher Yes and it makes no difference. It crashes when encoding textures. I build my lighting as I go along so I don't have too many objects to build lighting for. At some point, the program starts crashing when I only have a handful of new objects. When building, it maxes out my cpu and my gpu back and forth and it shouldn't.

Thought I would throw this out there, Opera GX has memory/cpu/network controls so you can choose how much of each it's allowed to use regardless of how many tabs you are running. Just know that if you don't give it enough cpu power then 4k videos will be choppy.

Hello) I was wondering why this have been happening in my project on GTX 1050 TI. This video was helpful to made it clean. And now i start to thinking about new GPU. Theoretically, i could buy something like RTX 3050, 3060 with my budget. Considering the 12 VRAM in the second card i would love to buy 3060. And what you're think? Or maybe it would be better to save some money, in order to get 3060 Ti with 8 Gb, but with +20% better performance? Because, honestly, I think that in my case 3060 is the best choice if i want Nvidia card for work, and RT.

To be honest, i haven´t had the VRAM in mind since i switched form 8 to 24 GB and i haven´t had such an issue with 8 GB before. The hint with Virtual Texturing saved my life :). Before i had up to 22 GB Vram usage now i have 12-14 GB, everything runs fine again. Thanks a lot
