Do any of you also get this weird white light with ghosting on certain walls or huge purple walls blocking your view from certain angles?

I failed to record it but I'm wondering if this is a Fallout 4 thing or my GPU is dying.

Not seen that in my game. What setting do you have Godrays on? I really dislike the over the top effects of it on any setting higher than Medium.

Big purple walls means your machine is running out of memory. Save and reboot.

I do. Is that a possible reason?

That is a strong possibility and not a GPU thing. Thanks for this suggestion. I have a tendency to run chrome tabs and not close them during gaming because im an idiot.

Well, I overlooked the "Purple" effect. As Euro mentioned, how much system memory do you have? 16 gb? And 8 gb of video ram? if so, then you should not be running out of memory unless maybe you have a lot of crap running in the background.

But of course, Windows virtual memory, does need enough free drive space, to function well. As a min, keep 10% of your drive's capacity free for it to work well.

My understanding is the purple wall thing happens when you play for a LONG time without restarting or rebooting. The temporary memory of the game begins to get exhausted and it can no longer draw detailed terrain. So instead you see the "foundations" of the world which are big and blocky.

It might be something else of course but that's one possibility.

A similar thing can happen when you fly in a Vertibird through complex terrain on a low spec machine (or just one that is tired). In that case your machine can't load the new detailed terrain fast enough and just loads the crude blocky terrain.

The purple part is because that's a popular masking/transparency colour for game design, due to relatively few textures or other colour designs including large amounts of bright purple. So if something like a texture completely fails to load it shows clearly as that default purple.

Some other games might have a different colour or shade (like blank white or bright green), but purple is apparently what Fallout 4 uses.

i have a 3070, should it be doing that? I was playing Elden Ring a few nights back, and there's a similar "fog" wall (not the same as a boss' fog wall) blocking a pathway in a cave dungeon. I was worried my gpu was dying.

3070 8gb vram. Perhaps I was playing for quite some time without restarting. One prominent place it happened in was Diamond City near the farm/Valentine's office.

I think your GPU is fine. Stop keeping those multiple tabs open and see if that helps. A computer does not have unlimited resources.

I always shut down my computer at night before going to bed. Been doing that for decades. I think it helps to flush out crap from your system memory. Whatever it does, that practice has worked well for me over the years.

My older system, a I7 4770, GTX 1650 Super, is 11 years old and still works just like it did when new.

It doesn't hurt to check on the GPU as well, and take it as a reminder to keep your machine in good health. Temperature checks, dusting out, drivers up to date, and all that.

The white light with ghosting part is a symptom similar to the purple; instead of drawing a default colour, it means the undrawn space behind the object is showing through (with trails of previous frames not being cleaned up as the view shifts because that section of the screen is already supposed to be covered by a texture).

My current machine has also been running for years, but once or twice I've needed to redo the conductive paste on the CPU to keep it happy.

So the white light that is also dizzying to look at is a product of memory issues, got it.

I recently replaced my thermal paste and dusted my entire PC because I had to move to a far away place, meaning I had to get it shipped to me so there's the minor worry that it might have been shaken up during transit.

It sounds like you should be good as far as other physical issues go, and you should be able to easily check if anything's loose. If it was anything catastrophic, you'd be getting more than occasional texture issues, so just keep on top of the software side of things as well, as wtiger27 and The Inept European have already said.
