Does anyone have the same problem?

for unreal the things like trees and grass make the game slow. i see from game reviews that the games are slow i have a fix in my copy and paste note for unreal 5 game making:

here:

find the amount of texture memory your game uses first.

in the console on the bottom of unreal engine, type this:

r.streaming.poolsize 1

you will see this message: "texture streaming pool over budget" see the number. play the game wander around and write down the largest number on the screen.

now close unreal engine and go to this file;

Program Files\Epic Games\UE_5.1\Engine\Config\Windows

WindowsEngine.ini

PoolSizeVRAMPercentage=70

70 percent this is the default value. if you find the amount of vram your videocard has for me its 8GB, if i take 8GB and find 70 percent of that and add in the largest number over budget i see if i can increase the 70 percent to 80 percent.

if i find 80 percent of my videocard + the streaming pool size is less than the total amount of vram my videocard has i change 70 to 80 save the file and reopen unreal editor and its faster loading the map everything seems faster.

if everything runs good then leave it at 80 but if the game is acting weird now put it back to 70.

----------

if you get "texture streaming pool" error. make note of how much you need to fix the error it will say in the message.

open output log, type "texturequality" in output log to see the number beside texturequality for me its 3.

in the unreal engine config folder, find this file BaseScalability.ini, open it and find [TextureQuality@3] see the 3 you saw in the output log.

set r.Streaming.PoolSize=1000 higher than 1000, the error message showed how much more, set it a bit more than the error message amount. i set mine to 1500 and its good for me now.

save file close and reopen unreal engine and the "texture streaming pool" error message should go away.

-----------

in unreal engine, when you put in foliage especially trees, you might need to speed up your pc, below i show how i did it.

now for all the foliage i got from BlackAlder and Quixel Bridge,

tweak 1:

__________

i also open the cyan colored static mesh and search for "uv", and then uncheck all the boxes.:

use full precision UVs

UE4Compatible UVs

Generate Lightmap UVs

Generate Lightmap UVs

i do this for what i get from quixel bridge and blackAlder and Medieval Dungeon,

every cyan colored static mesh i can.

it takes a long time so i do this in a separate project that i can migrate the files from into a working slash project.

tweak2:

___________

select all icons with the green color strip,

right click,

asset actions,

bulk edit via property matrix, then do these settings below:

custom navigable geometry = no

evaluate world position offset = unchecked

cast shadow = unchecked

save and close the property matrix

tweak3:

_______________

in project settings:

in rendering:

dynamic global illumination method = none

reflection method = none

anti aliasing method = Temporal Anti-Aliasing

frame buffer pixel format = 8bit rgba

tweak 4:

_________

in quixel bridge:

use low quality from quixel bridge,

heart the ones you download so you can redownload them from favourites instead of searching for them
