P3Dv5 Excessive vRam usage

[GSalden 4,689]

Here I have a server with a 2080 Ti 11 Gb that drives two 4K displays in NvSurround.

Also I have a left view client with a 2080 8 Gb  and one 4K display.

V4.5 is running very well .

I fear that both graphics cards do not have enough memory for V5 to have at least the same detail as in V4.5.

Any suggestions?

Bought an RTX 2070 Super a few months ago and it is funny and hard to belive it is too weak for V5 😮

Buy two Titan RTX's 😆

This is one of the reasons when Nvidia came out with their new 2080 card I couldn't believe it, only 8GB of VRAM?! We've had 8GB VRAM cards for 5 years or more... being flight simmers we are going to hit that VRAM limit sooner rather than later.

Wait until it is fixed. Even if it takes a year. That is not a compromise you will want to make.

VRAM is not expensive at all.

A 2080 should have had 11 Gb and a 2080 Ti should have had 16 Gb...

A Titan Is 2x the price of a 2080 Ti and perhaps $ 200 more expensive on VRAM !

The way NVidia controls the gaming industry is not always the best for us..

Yes, unfortunately a rip off I know, but probably the only way to beat the VRAM OOM's unless LM provide a fix.

But that will probably mean compromises in visuals which is probably what is causing this - with improvements

comes increased requirements.😏

But this is just ludicrous.

Currently you can't even run it on minimum specs.

If you are on minimum specs then yes it is ludicrous. If someone was using 6 to 7 Gb in v4

and is now seeing OOM's with 8Gb of VRAM then that is understandable which is what I meant!

I have a GTX1660TI with 6 Gigs. Bought it last year together with my Rift S.

Performs adequately in V4, excellent in V5.

But runs out of memory in V5 in no time. With the SAME graphical settings. I did not crank anything up.

Do you have the new Atmospheric settings turned on?

Currently yes. 

That makes indeed a difference of one gig in VRam.

However that is WITH cloud coverage. The OOM's I had were WITHOUT any clouds.

Do you know how much VRAM you were using in v4. Maybe that 1 Gb is just enough extra

to push it past the limit of your card. Just a thought - I am no expert. LM are really the ones you

need to complain to, I was just stating an opinion which seems to be a dangerous pastime at the moment🙂

In V4 I can go up to about 5.6 before it turns into a stutterfest. V5 only recognizes 5 and says bye bye as soon as I reach 4.9.

I think you 'll find that is because of DX12. It handles VRAM differently and apparently doesn't allocate as much

to p3D as before? Sure I read this somewhere in the Forums. Maybe someone more technical can confirm this.
