[In]formal proof of the limitation of 1.5GB VRAM at 1920x1200 resolution

[bhavv]

People's been saying of graphic card might use more VRAM if available, but not necessarily need them?

There are lots of games use above 1GB of VRAM, but the performance different is just 0-3fps between the...say 6950 1GB and 6950 2GB.

Exactly. People keep on posting their 2-3 Gb cards using over 1700 Mb Vram, but when you put the same game, same mods and same settings on the same GPU with less Vram, you get exactly thew same performance, just around 2 or 3 FPS less.

Why people cant notice this obvious fact which has been proven countless times I'll never understand.

I used 1.7GB in BF3. 2560x1600 Ultra.

But what happens when i run crysis 2 at 2560x1600

Thread title says 1920x1200.

isnt it all based on the software?

1. If the software knows there is more Vram availble then it can load more textures into that ready for when needed meaning less swapping of data.

2. If theres not then it loads what it needs and swaps out some when not in use for that which is needed.

3. Not enough Vram so it simply wont run or running to high settings meaning lots of swapping happens and you get lots of stuttering and freezing while data is swapped.

1st and 2nd you are fine, 3rd you need more Vram. People getting different results for Vram usage just fall into those 3 categories, Simples

I got no issue agreeing that having more VRAM could benefit games, however what I can't stand is there seem to be a start of trend leading the average Joe by the nose into believing VRAM is more important than GPU grunt at 1920 res...that is what I really cannot agree with.

You either:

a) still don't agree that lower average fps is NOT the only symptom of vram shortage. still don't believe in the tale of "lag spikes / stuttering".

b) partially agree with the tale of "lag spikes / stuttering" but practically take performance / price ratio into account, not considering vram seriously, because GPU power is of first priority.

c) simply making fun of me, just like bhavv

we need a serious review about vram impact at 1920*1200 compared to the 1.5gb (min, avg, max fps, lag spike or stuttering? etc...) Maybe repi know more things about 3gb version used in bf3.

Wait for reviews from Techreport. They are still finalizing their standards, and when they have the same core of different vram size they'd do the tests in this way. I bet some games would get more or less serious symptoms due to vram shortage, other than lower average fps.

If Vram is as important as you keep on saying it is, then isnt a 2 Gb GTX 560 ti a vastly superior card to a 1.5 Gb GTX 580?

According to you, GPU speed, Stream Shaders, and Memory Bandwidth are all meaningless compared to amount of Vram. Vram is the only thing that improves performance

And why dont you go ahead and buy 2 Gb GTX 560 tis if Vram is so important? Why dont you write your own reviews with legitimate Vram comparisons if this issue is so important to you?

You are misquoting or misunderstanding me again. I'd just repeat again:

a) GPU power is the dominating factor in terms of performance;

b) sufficient vram is the necessary condition to obtain consistent framerates and unleash the full potential of the GPU power.

When you see only 1000MB vram usage on a GTX560 Ti 2GB SLI setup, in certain games like BF3 or Metro 2033, where a GTX580 can get readings of more vram usage, then it's poor driver "optimization" which manipulates thrashing according to the GPU model regardless of vram size, which is a sad and funny thing.

And now what are you smoking or talking about? No one has ever seen this, are you hallucinating or something?

You've yet to even use or look at 2 Gb GTX 560s, so why are you making things up?

No sorry, I'm not buying this after reading all you ever type.

You are 100% fully certain that Vram is the only thing that improves performance, as from your posts in the 1.5 Gb vs 3 Gb GTX 580 thread.

simply making fun of me, just like bhavv

Seriously...get a hold of yourself. You see everyone that disagree with you as "personal attacking" and "making fun" of you, when you yourself keep on trash talking how bad 1GB cards are when people still happy with the performance of their card, and calling people who think it is not yet the right time to upgrade to cards with more VRAM (due to this gen cards being hardly faster than last gen) "defenders of 1GB card". You keep turning discussions into something personal...if you are like that, you should really stay away from forum and spend more time in the real world.

Like we all know how SandyBridge i5/i7 is faster than last gen i5/i7 and at a much lower power consumption, but you don't see people that got a SandyBridge i5/i7 system keep rubbing it in the face of people that own last gen i5/i7 and keep telling them how crap their i5/i7 are.

Most people who already got a 5850 1GB or 5870 1GB simply don't think it's worth spending over £100 upgrading to 6950 2GB, as they believe upgrading to...say 7950 2GB would be much better value for money. If you are donating £100~£120 to every 5850 1GB/5870 1GB owners for them to upgrading to the 6950 2GB, they would most likely very happy do it; but since you ain't doing that, all you are doing is keep on banging on something without a solution for most people...so in one word- pointless. May be it is easy for you since you seem to have plenty of money to spend on graphic cards or PC hardwares etc, but I sincerely wish you to remember there are people that have limited budget to spend on PC hardware, as they have other priorities, such as mortgage to pay, family to feed. Not everyone lives in lala land with unlimited money to throw at graphic cards.

GTX560 Ti 2GBs don't have sufficient GPU power, and don't support TRI-SLI/Q-SLI, and would be incapable to run games like The Witcher 2 with Ubersampling.

I see no point to write my own review, as it would be regarded as rubbish by people like you.

That's according to the posts by other people in other forums.

You have no point to write your own review because you have absolutely no evidence to back up your claims.

If you see no point to writing a review, what is the point in making all these threads and posts about Vram?

That's according to the posts by other people in other forums.

Which forums? Why cant you even link to whatever you are quoting from?

Why dont you discuss this issue on the official Nvidia forums, or on Xtreme Systems so I can see you get eaten alive?

 

[Scougar]

What's the point though, when it suits him (harmony) he says it's all subjective (with regard to stuttering/lag) and throws dismissive remarks about what people want. He can't have it both ways.

In my opinion you need to test 'VRAM stuttering' on a single card, and not in SLI. This will rule out any potential SLI driver issues that get perceived as a VRAM issue.

There is another minor issue as well which is that your VRAM that is in use by the rest of windows is of course variable. This can cause issues if you don't shut things like MSN or whatever down first as that small bit may take you over the limit.

There is no doubt that there is a negative effect when faced with a RAM shortage of any type, I just don't like the scaremongering.

A forum in which you have been banned and account deleted.

Why not Xtremesystems: because they split up NVIDIA and ATI, while the games forum is almost dead.

I might register an account in the NVIDIA official forums and post about this problem but who would care? If they admit this problem, then they admit that 1GB is a bad design, which would affect their sales.

a) If I test it without SLI, then the average fps is not high enough to contrast with the lag spikes. I've always been claiming that more vram is recommended for SLI/CrossfireX, not for single GPU.

b) I do know that there are other factors to affect vram usage. The easiest way to increase vram usage is to open many high resolution pictures. When I did my tests, I closed everything I could.

Really? Why cant you name which one rather than making stuff up? I cant remember being account deleted from any hardware forum? The only ones I use are this one, XS, and in the past Tomshardware.

Why cant you even post a link?

Oh, and I just checked my account on a major competitor sites forum, thats still there too.

Pretty sure. It was there I saw that your IP address was from Saudi Arabia (perhaps you were travelling or VPN bouncing). When I tried to look for your account there later I could not find any record - all banned accounts get deleted regularly, and I think you were one of them.

LOL what major BS. I've never been to Saudi Arabia, nor is my IP from there, and I have not the slightest clue what VPN bouncing is.

Can harmony please get in trouble here for slander or something?

Again, name the forum and stop **** stirring you major troll.
