Running out of VRAM on RTX 3070?

Rubber Dinghy Rapids Broo
I just swapped sold my Radeon VII after buying an RTX 3070. In benchmarks i've got around 10% extra fps and an extra £200+ in my pocket and play at 1440p ultra.

One of the games that me any my brother play through a lot is Shadow of the tomb raider, but ive noticed sometimes when playing and especially when running the benchmark just to see if there was an fps increase, that the texture of some of the buildings change, shadows randomly appear, and items popup in the background which I find extremely jarring every time something happens. Afterburner tells me its constantly running at 7.5gb VRAM.

Am I experiencing this because of the lack of VRAM?

Are there any recommended settings that I can change to try and ease the VRAM usage if this is the problem?

I did also try out RTX on ultra and high, but noticed no difference other than the framerate counter being halved, so I assume that any benefits for ray tracing aren't visible in this game.
 
Welcome to nVidia imo, AMD just seem to get a better LOD generally at what they do (probably why they're at the top of the quality charts but not the overall FPS ones!). I certainly prefer my 6800XT over the 3080 I had, it's just something sometimes you can't quite put your finger on but it's just....better :)
 
I have noticed that my ram usage is a lot higher as well now, and im getting close to my 16gb limit. Should I put in an extra 16gb to see if that improves things?
 
IQ is better with AMD, no doubt in my mind and I've got a 3060ti and I'm very happy with it, but years of AMD cards before it and no doubt in my mind, AMD IQ is better (DLSS and RTX aside), I couldn't speak to VRAM usage however.
 
Unfortunately I can't go back to the Radeon VII, so i'll just have to wait for a 6800 to become available. Are there any settings I could turn down, so building textures don't change in the distance, and objects and shadows don't appear out of nowhere?

Probably run out of vram if you are getting excessive pop in

the 3070 is really a 1080p card simply due to its limited vram
 
Would overclocking the memory potentially make a difference, i've just realised that i previously put an overclock on it when I bought it and wasn't noticing any pop in but had an issue with afterburner after downloading someones OSD file, and it has reverted back to stock clocks. I'll try putting the overclock back on and see if that fixes it.

Sounds ruined, send it to me for £200 and we'll say no more about it.

j/k

But I am hoping that putting the overclock back on solves the issue until the AMD cards are back in stock. I don't play games a lot but when I do, I want them to be perfect.

Yes, even if not technically running out of VRam with more of it games can run better as cashing textures in VRam is MUCH faster than streaming it off a Disk or out of System RAM.

In the longer run the 8GB VRAM is going to be a limitation - I do fine at 1440p in anything out now but stuff like Cyberpunk really do tax it at 4K and some other newer games you don't have a huge amount of VRAM left over at 4K without turning down settings.

Which is why I hung out for an FE as blow spending any more money than that on an 8GB card now and probably will relegate it to my 2nd rig sooner than I normally would depending how things pan out.

PS as before if people are seeing significant IQ differences (other than in games that automatically adjust settings to handle VRAM limits) between comparable AMD and nVidia cards something is wrong on their end. There is no difference in LOD, etc. unless you are running into automatic framerate or memory management situations.

This has been tested to death and there are certain YT channels who'd be all over it like a rash if it was true.

Yes, it's a combination of less vram and lower memory bandwidth - but not for object pop in, that's usually just a software limitation of current-gen games. The main thing you can do is reduce the texture quality, though enabling raytracing further requires more vram capacity & bandwidth. Sometimes it's the game's fault (e.g. in Control the texture streaming is broken on all setups), but not applicable to Shadow of the Tomb Raider. The raytracing is more subtle in SotTR but if you can play the child Lara section before you start climbing the building you can definitely tell it has a good impact, particularly on the character if you pan the camera around.
