12GB vram enough for 4K? Discuss..

Sounds like Tommy is one of them who sits 2-4 feet from a 65" display :cry: :o

Amazing as the local system issue and it works fine on my system card gets played many times with AMD hardware and software over the years when a person wants help and one has to be subjected to blaming, gaslighting and trolling.

Especially recently despite "EVERY" site and most users posting about issues with both hardware and software for rdna 3 ;) But remember, "fine wine" :cry: Or wait, better yet, "*those review sites are wrong as I can get 20+% performance with my setup"

*setup consisting of the best of the best for every component, highly fine tuned, liquid metal cooling, with AC cooling on the system, with a fresh install of windows for every benchmark done

;) :D

GPU DECOMPRESSION AND RTX IO

Decompressing assets on the GPU is still being worked on by Microsoft and graphics card vendors. Nvidia calls their GPU-based decompression API “RTX IO”. This is not currently available and has no confirmed release date as of today. Once this feature is released and implemented into games, assets will be able to be copied from system memory to VRAM in a compressed state, where they will then be decompressed by the GPU. However, the compressed assets must still be loaded from storage into system memory via DirectStorage first. The CPU will still handle these IO requests. The only change is that the CPU will no longer have to handle decompressing the assets.

Yes, the main benefit of DS for PC gamers will be how much CPU % it frees up, the rest is mostly irrelevant.

Vram requirements are going to be impacted as well. As the reddit post suggests:

Current framework: copy compressed assets on sys ram. Cpu then decompresses and pushes the output on vram

Rtxio: copy compressed assets on system. Cpu then moves them as-is to vram in compressed state. The gpu then decompresses assets in flight
 
direct storage in the long run means:

Less work for CPU
No more decompression stutters
Less RAM needed for gaming
Less VRAM needed for gaming


But these benefits don't mean anything for a very long time - because until most gaming PCs can handle direct storage, game developers have to program games the way they have been doing which means you still needs lots of vram and ram and a good cpu

Less vram? They are going to be storing the decompressed and the compressed textures at the same time. This is more vram.

Edit: I guess there is a way that it could be used to help lower vram graphics cards. Where they aren’t able to load the full scene they can have the partial scene and quick access to other parts as the player approaches them. Rather than having the full scene and then extra pieces beyond this ready to access which of course would need more vram.

If in doubt, buy an RTX 4080 FE with 16GB for £1,199.

Or 20GB RX 7900 XT for ~£900.

The moral of the story is that more VRAM will always cost you disproportionately more than it should, in terms of the performance gained.

This makes people frustrated that not everything is perfect, and we see these threads.

They could make a cheaper RTX 4080 with 12GB and the performance would be almost the same.

/thread.

There's a magical land of plentiful and cheap VRAM.

No one has to suffer the trauma of a single frame out of 10,000 being dropped.

The days of 8GB VRAM were the dark times, no one speaks of them now.

Yes, it will free up some vram but imo this is a minor benefit. In general we're not very vram-starved on desktop and there's a lot of easy tweaks to adjust it when we are (on the dev side), or indeed plenty of cards to choose from that aren't low on memory.
