Does VRAM actually change much?

[Kanna]

So I tried to use a 960 2GB in my PC with a 1060 3GB equipped before and settings were set to it and when testing on GTA V VRAM was at 2500MB and the game ran no problem and did a benchmark where highest fps was 85 or 90 and lowest was 53 fps or is it that GTA V can be much CPU dependant?

was it the exact same settings?

and what cpu are you using

The settings was the exact same and there was no ask to change anything either since I had the ignore VRAM limits on from before, my CPU is as it states in my profile an i5-8400

yes GTA is known to be very heavy on the CPU and care a bit less about the GPU.

 

And while your FPS may be ok with the less VRAM is will make a difference with things like buildings and care suddenly popping up as they fail to load fast enough.

Probably some sort of caching to the drive or RAM. Ram does not magically appear it will probably slow you down.

Didn’t notice much difference from my 1060 it even felt faster / better

Is the caching disabled or enabled by default?

What is said was that  ignoring VRAM limits you will not use MORE memory on the GPU, because it is not there. If you use more VRAM than you actually have the the extra memory is a trick probably caching on the disk or eating up RAM. It should be better to use VRAM limits

Why should ram / disk caching be avoided? Except than it’s slower

Just because its slower. It will lower your FPS, you game may stutter, it will be worst in general. GPU memory is much faster than your system RAM

Well the weird thing is that it ran with less stuters than it did with my 1060 and this time the buildings actually was there

Having more or less VRAM does not change your performance, as long as you have enough. Just like system memory.

Actually without even ignoring memory limits any game can go above what the VRAM has. That has been a feature since early as windows XP and is somewhat critical for modern gaming. AMD version of it is/was called HyperMemory. This feature is now baked into all Nvidia and AMD drivers for a long time. Whole point of it is to reduce stutters and pop in from loading assets into RAM instead of pagefile.

So I could in theory use the 960 and not notice a big difference in performance except the few mhz in difference

Missed one word that changed meaning

You can't compare Mhz between the 960 and 1060 because they run different architectures and core configs. You will notice less performance when switching to the 960 in most games.

Ohh yeah the architecture, but I think most games I play I wouldn’t see much performance difference except like cold war

GPUs have GDDR5 or 6 directly onto the card memory lanes. A PC would have DDR4 which is slower and not directly onto the GPU. How can this not slow things down and be an improvement ?

A video card with HyperMemory typically is slower in 3D benchmarks than a similar video card which has its own discrete video memory.

My idea is that it makes it being able to actually load instead of just stop loading

I dont see how I said otherwise? Caching assets into RAM then moving them to VRAM in a calculated manner will provide MUCH better experience than trying to load assets into VRAM directly from storage device.

Well I doubt it will help with stutters. Its more like a marketing idea to make cheap GPUs with not much memory  and eat up system RAM naming it HyperMemory that ordinary people don't know what it even means, making it sound like a feature other GPUs don't have.

Yeah I guess windows and whole lot of game developers dont know what they are doing and utilizing this feature for absolutely shits and giggles. If we didnt have this feature you wouldnt be able to play games like FH3-FH4 with AA enabled on any card with less than 16G of VRAM.

FH4 would shit itself
