Hi!

Considering that Bethesda recommends 3-4GB vram for F4 makes me wonder: How much vram could modded F4 actally need? I do not have any evidence but i bet people doubled vram usage with texture mods and such with Skyrim. And since they upgraded the engine, i bet we can have bigger ram and vram caps than 4GB.

What do you wastelanders think? Will 4 gb vram be enough for heavely modded F4? What are your predictions?

Sidenote:

I myself love to use mods for games, i modded the hell out of skyrim and F3/nv and the difference to vanilla was like night and day. I will surely use a lot of mods for F4. That made me think... I originally decided to buy GTX 970 for F4 release but at my country, the R9 390 8GB is same price or even lower... and since games use more and more vram these days, i kind of think that 4GB and more is a good backup resource to have. I probably never use all of that 8GB (even if i plan to go 1440p next year) but, hell, who uses all of their 16GB of RAM while gaming... but it is still nice to have just in case. Even if F4 vram usage goes up to 4.5, im still better off than with 970. And, there is this rumor that current amd cards will have better perfomance with dx12 than nvidia cards. But, it is not what i wanted to talk about in this topic.

Vram wont be the issue when it comes to mods but actual RAM in your pc which bethesda says needs 8gig minimum and recommended because skyrims biggest flaw was that it only allowed you to have a maximum of 3.1 gig of ram before it would crash.

But surely vram is also needed for large texture mods and stuff like that... and if F4 already uses 3-4 gb then it can only get bigger. Or am i not understanding vram properly?

oh dont get me wrong Vram is needed to an extent but when it comes down to it, its all about actual memory that matters. It shouldnt matter too much with fallout 4 seeing as its a 64bit program ( you must have a 64bit OS to play the game) while skyrim was a 32bit program thus it has a max limit of 3.1gig of ram and if it went over that then the game would crash

Skyrim was an 32 bit program and could not use more than maximum 3.8 GB ram.

Fallout 4 is 64 bit and can use 16 TB I think.

On 64 bit games with lots of large textures vram can be an limiting factor.

I noticed this playing elder scrolls online. overall my graphic card was good enough with 1GB but in cities with lots of players it had to load all the armor textures from main memory or disc all the time.

However this did not cause too much lag the game just loaded low resolution textures instead and later the high quality ones so it was mostly an visual effect.

Googled a bit and learned that unmodded skyrim used around 1gb of vram, highly modded one was said to go up to 3GB. So, three times the size. I bet it does not mean that F4 can go up to 12 GB of VRAM , but i can imagine 6GB can be reached with 2k textures and many other modsl like that.
