@Nexus18 you've not got 8gb so you are never going to know past your opinion that it's enough, both gpus are being used so Iv'e got a fair grasp about what they can and can't do.
@TNA probably knows as he's used both like myself
, the 80 isn't
that much faster than a 70, therefore an 80 can't magically up loads of settings over the 70, its marginal at best but its extra 2Gb is clearly beneficial.
Dlss while being a great feature to have, wasn't the magic bullet then, it's better now, but if you had used it from the start you would know it got switched off and dialled back settings, therefore it couldn't help the 8gb limitation as you wouldn't be using it under 4K anyway.
True, I can't speak from first hand experience anymore since upgrading from my vega 56 to the 3080 but I know the games well and what certain cards are capable of and what settings to look out for
If you're having issues because of vram, it's rather simple to fix, you just reduce settings, mostly any kind of texture or/and shader setting to remove the vram bottleneck, chances are, you probably won't even notice the difference dropping from "ultra" to very high/high texture etc. setting(s) anyway. When I played cp2077 on my vega 56, I encountered vram issues i.e. frame latency and micro stuttering was all over the place but the fps I was getting was crap too due to the lack of grunt (even without ray tracing since no support for the vega 56), around 40 fps thus I had to reduce settings to get the fps range I was happy with i.e. at least 60 fps, which in return solved the vram usage this removed the issues with the inconsistent frame latency too.
Essentially, Vram and raw grunt go hand in hand, sure, it would have been nice for both the 70 and 80 to have more vram but ultimately, the 3070 having an extra 2GB would not have made that "much" of a difference to its perf., likewise with the 3080 having 2gb more vram, as evidenced on this
page with the comparisons of the 12gb model to the standard 10gb model (tldr: performance difference between them is all from the MSI AIB 12gb model having a much higher boost clock and better specs across the board)....
Just watch the videos above showing 3080 vs 3070ti and 3070 perf. too, a 3080 is a rather substantial improvement over a 3070ti 8gb regardless of vram being used..... A 3070/ti for an acceptable experience (imo) will have to reduce settings regardless of its vram usage, again, subjective this though as everyone is happy with different fps levels, most noticeable and important figures is the lower end i.e. 40-50 fps is a noticeable jump, more so than going from 110-120 fps.
Don't disagree, dlss when it first launched was a pos but what does that matter now? Not to mention when it first launched, 8gb was perfectly fine back in those days so there wasn't as much of a need for it.... It's superb now.
Direct storage should in theory reduce vram usage too, problem is, we probably won't see any games anytime soon and likely will have the 50xx series of cards then.....
