The Titanfall BETA has insane VRAM requirements!!

[Orangey]

I say this a lot but why are we assuming you need that much just because the framebuffer is full? Maybe the space is just flagged as available and overwritten as needed. Maybe certain textures are weighted higher and don't get cleared, so the next texture is allocated free space instead.

Does anyone know how VRAM actually works?

 

[Woden]

Why would such an average looking game take up so much vram. Is this not just poor programming?

Its almost as if it is some sort of unfinished product eh?

I have a GTX580 and when I turned Textures up to high it was hitting my VRAM limit of 1.5gb (obviously) but was still smooth enough, weird.

Doesn't really matter if it hits your VRAM limit, what does matter is if the vram isn't enough to hold all of the textures, geometry and other data needed to render the scene.

A GPU will cache and hold in vram all data it accesses, there will then be garbage collection algorithms that choose what to keep and what to get of in vram when more needs to be loaded in because the limit has been hit.

If a scene does hit the vram limit then data needs to be streamed from ram at which point you see the total tankage of fps down to single digits.

Published on 14 Feb 2014
A quick render of a multiplayer match on High Settings, 2xMSAA, Double Buffered Vsync (i'm on a 40" 1080p hdtv so vsync is on to avoid tearing)
Recorded using Shadowplay, Fraps loaded for fps counter.

As you can see it's my 1st go at the game and i was working out what the hell i was doing lol.
It's a lot of fun and i can't wait for the final release.

I Also tried the game on INSANE settings it ran pretty solid at 60fps until i was being attacked by multiple titans then the fps briefly dropped down into the 30's

CPU: FX 8350
GFX: MSI GTX 770 LIGHTNING
RAM: 16GB GSKILL RIPJAWS X
PSU: CORSAIR 700GS
OS: WIN 7 64 BIT

I asked the guy if it was a 2GB 770, which he replied it was. Seems 2GB is still fine for 1080P to me.

If the game Devs thinks that level of graphics need more than 2gb of vram they must have some really poor software programmers.

I am downloading the beta now, and I will give it a test with GTX 670 2GB. Should be fine at 1080p.

Basically this

 

[~>Dg<~]

remember, youtube takes a **** on graphics when you upload.

also 1080 i think youll just scrape through any higher i think you having issues.

as said ive been playing it earlier with a guy having issues. hopefully its sli and not the 2gb.

3.7GB+ VRAM usage

Yes, that's why its called a beta, pleased you are here with your useful insights. Its an old engine and its nothing special to look at so no reason to see these issues even at this stage of development.

Still a fun little game but I can't bring myself to pre-order it....?

I think Woden was injecting some humour into this thread

 

[Snougar]

Been playing Titanfall Beta and I'm on a GTX 760, and it runs flawlessly, even with Insane textures and 4xMSAA at 1920x1080. Not seen the GPU ram usage go over 1.4GB so far. Flat out 60fps (Though the game caps FPS at your screens refresh, regardless if vsync is on or off).

12GB DDR3-1600

I think everyone else saw through the sarcasm. More importantly, what makes you think this is an old engine? I assume being a new company and having split away from activision, respawn would be forced to start again. You can tell what it is born out of but assumed it would be new...

 

[Orangey]

It's Source with bolted-on extras.

 

[Boomstick777]

Seems with this game GPU grunt is needed along with vram, no good having a 4GB GTX 660, as in a 2GB GTX 770 will still run it faster..

2GB seems fine for high settings 1080P/1440P and 3GB for 4K+

Let's hope tiled resources helps help with vram requirements in the future.

Haven't been posting much lately due to the putrid bile/attitudes@oCuk(WHICH IS SHOCKING BTW!, A BIT MORE RESPECT FOR USING OcUK'S FORUM PLEASE, IT'S TARNISHING OcUK'S BRAND!)but here goes.

None of the gpu guru's here do, none, but they have a firm stance on exactly how it works.


It turns into fingers in ear mode, usually what flavour they 'gurus' favour.

Maybe the space is just flagged as available and overwritten as needed. Maybe certain textures are weighted higher and don't get cleared, so the next texture is allocated free space instead.

To be clear, yes I have a 290X, but don't count the below as a- tommy is AMDv Nvidia, Nvidia have the same counts of Vram models, it's 'maybe why' from a neutral pov.

Maybe it simply fills the buffer because it can.

Maybe it simply fills the buffer in order to swap textures over far more quicker which in turns lowers fratmetimes=smoother?

Maybe by doing the above, it increases the number of textures in the buffer leaving a lesser hit on fps, giving increased performance for the next higher IQ setting-+2MSAA on similar performing gpu with +1Gb extra?

Maybe if your gpu approaches the limit, you can knock it down a touch of IQ, as you will revert to faster fps, it simply doesn't matter it isn't really going to be missed.

Regardless your gpu, if a future title exceeds your vram, it doesn't have to go in the bin, it's either-upgrade time, or for those that purchase for 2/3 years-well it's still going strong and will still be highly playable with compatible settings.


When all the shouting stops, regardless what you use, 5870/470 upwards will play anything out there in some shape or form.

Exactly, it's a beta. We don't know what they have done to the source engine. What extra gunk is in there to help with debugging? Have they optimised assets yet? Will a driver update from AMD and nVidia improve things?

 

[Rangerjr1]

Idk why this is even argued at all.

1. 2gb isnt enough, you are bound to see choking or low FPS as a result at 1080p maxed out (Try without Vsync, should make things even worse).
2. 4gb GK104s? Crippled bandwidth makes it pointless.

 

[sieze2]

Look- I just played it at 1440P with x2 MSAA with it turned on and off. Both times it used all the 3Gb of VRAM. Now I know MSAA uses an extra 700mb minimum on most games, therefore I can tell you there is lots of caching going on (as there should be with a well programmed game)
