Out of video memory in UE5 ? Whaat

it is all very weird… Yes there are quite some object at the moment but that did not affect it yesterday, i do not yet use Nanite on any meshes, i have scaled down Textures appropriatly to 2K MAX and most are 1024 and smaller object 512.
Total actors [3451] but that includes the Landscape streaming

i record my progress so i can edited them at later time. my latest video
Here is a video from yesturday showing off the cafe i build:
https://www.youtube.com/watch?v=8IjWob1r7u0

its a Raw upload directly from Radeon recorder, even youtube recognizes it was hitting 60fps…

i raised the mem buffer to 3200 as i was getting low mem pool, which is understandable…
but anyhow as you can see its running completely harmless… (it was)

the game is Running at 1400p at 60FPS, the next day i implement LOD’s which got my game to 100fps with the VEGA 64 card at 1400 on EPIC settings…

But tooooodayy, it all went heyhwire after that problem with the Landscape now the whole scene is lagggy

this also occured after enabling the “Virtual Texture Support” and it Re-Build the textures…
