GPU Upgrade

[pilot21200]

Hey all,

 

I recently upgraded my pc 7800 x3d 32gig ddr5 ram, quest 3. I currently have the EVGA GeForce RTX 3080 FTW3 ULTRA GAMING, 10GB. I would love to get the 4090 but those prices are stupid and just paid for my upcoming wedding so no 4090 funds available. Really looking at the 4080 or should I wait for the 4080 super that comes out next month.  I only fly VR, is the performance worth going from the 3080 to the 4080 or the 4080 super if I can get one pretty sure they will sell out fast.

Since I got the 4080 my DCS experience has been transformed in VR (coming from the 2080Ti). Really up to you and want you want to shell out, but the 4080 is well up to it.

R u GPU bound now with your new processor or still CPU bound?

Gpu bound. Not a ton on videos with the 4080 in vr

I'd suggest to wait until the new cards are announced soon. Prices will drop hopefully on the normal 4xxx cards, and if they're worth it, you can get one of the supers.

what is wrong with the 3080?? Sure would like to get one of those as I only have a 2080ti coming from a 1080ti. if you have performance issuesin VR with DCS try reducing the rez at which the headset is at and also reduce the Hz rate..

Ok. I am surpised.  I have an i9 14900 and 4090 and a definitely cpu bound so go for it!

There is nothing "wrong" with a 3080, but I upgraded from a 3080ti to a 4090 as well and the performance increase is really significant. It´s in the range of 50%. VR needs VRAM...

Even though your suggestion is technically correct, you can`t just ignore the fact, that reducing resolution comes at the price of clarity/readability, especially of cockpit instruments and displays. Now this certainly might differ from aircraft to aircraft...maybe less of a factor in WW2 birds as oppsed to those with MFDs.

Reducing the refresh rate (Hz) of the headset...yeah, I absolutely agree with you on that one but:

- we don`t know which HMD the OP uses at the moment and at what refresh rate

- not all HMD even offer different refresh rates

- as for a HP G2 for example, the 60Hz offers nice and smooth gameplay, but the flickering is annoying at least and even unbearable to some

well unless I read it wrong the OP has a quest 3.. I run DCS at 30% rez and it looks fine with MSAAx2 enabled.. of course it looks better at higher rez but what I am suggesting works.. At max with my gear in Sig, I can only get 68-80FPS with a 30% rez so if I turn up the rez much higher my FPS drop and I get stutter..

Well I must not notice the flickering anymore but I would rather have smooth gameplay then run at a higher rez and have stutters.. it is really not too bad at the lower heck I would be happy to be at 50-60% rez as that seems like the sweetspot but with my 2080ti this is not gonna happen..

Hey Johnny, which are your pc specs, and which vr are you using? I’m aiming at 4080, my pc has 64gb ram and  amd 7800x3d, my vr is the crystal. How many fps you have and which resolution? Thanks

[Johnny Dioxin]

I have the same as you - but I use mostly Pico 4, Index on occasion. I'll have to get back to you on the FPS as I've not flown since a couple of OB updates, but it was very smooth last time - think I was still getting 45fps with SSW. tbh I don't pay as much attention to the framerates as the frametime and how smooth it is - but I do keep some records now and then so I'll get back to you. I know it was 60fps in the Index.

This with Pico 4 in the F-16 using Virtual Desktop...

The frame rate is good, hope the same with the crystal, but probably would be impossible without dfr. Thanks

For VR, low resolution, when trying to identify targets, most certainly impacts warbirds the most, there is no radar to aid you, and you need to get close just to make sure you're not lining up your sights on an ally

I would get the full 90fps or 120, depending on headset, in quiet zones, when at altitude or at aerodromes. Once things kicked off it would drop to the half rate by the ASW or equivalent, but would remain very solid with no stutters.

After a recent 2.9 OB update (a couple of updates ago) I tested the P-47D and Mosquito at low altitude and got slight stuttering with both over dense tree areas and others were reporting the same. I don't know if that has been fixed in following updates.

Of course, you need more oomph for the Crystal, so it may not be quite so good for you anyway.

@Nightdare

Copy that…and you are probably right.

My whole point is though, that sometimes people advertise a certain setting/tweak as if it was the best thing since sliced bread without also mentioning the downsides or specifying their particular use case. I don‘t fly warbirds, that‘s why I simply pointed out my lack of knowledge in that regard and that they are „maybe“(!) not affected as much by lower res. 
The same happens often with regards to motion reprojection (ASW etc…), where people simply say something along the lines of „leave it off, it‘s bad“. Some people might not come to these forums very often and take such comments as a generally applicable „truth“.

But well…yeah…I digress….it‘s the internet, right…?!

Hi,

 

I want to show you all this link: https://www.3dcenter.org/news/news-des-3031-dezember-2023

It's German, but it will give you a good look, how the 4080 and the other GFX compare to each other.

I would go with the 4080. The super refresh won't be so far ahead.

 

Cheers

Thanks Nedum, but I forgot to say the 4080, not the super that is coming 

[Nightdare]

We'll see in the next few months, luckily I have my vacation allowance in may

 

I have been using Nvidia since forever, but I'm not a fanboy

The whole Nvidia 408/70 and 3/4060 debacle left a bit of a bad taste in my mouth and since 4090's will never be in my budget, the 7900XTX seems like a good contender for the 4080

...depending on what the supers will do price/performance

[Johnny Dioxin]

After the latest 2.9 OB update, I just went for a test flight in the Caucasus in the A-10C. No combat, just navigation etc, but active AI units. From the moment of battery on until battery off I had a rock solid 120fps in the Index.

Unfortunately, the in-sim framerate display is not working properly - it's been off screen since I updated to the OB a few months back, and you can't see fpsVR in screenshots - but I was completely gobsmacked. Res is 150% set in SteamVR - frametime for the GPU was around 6ms and around 4ms for the CPU. 1 single dropped frame in the 1 hour flight.

I tried to take some photo's through the lens, but couldn't get it right - though you can see some of the data in the one attached. Sorry for the poor quality - nothing I can do.

I was also looking at the 7900 XTX I'm curious to see how it'll perform against the 4080  my understanding the 7900 had the driver's addressed and there's no more VR issues. It's a never-ending upgrade process to get things to work properly then again it doesn't help DCS is on an old build frame

cheapest 4080 starts at €1150 here, compared to the cheapest 7900 XTX being €980

Better RT and DLSS and faster memory vs 8g more memory, bigger memory bandwidth

...But I'm running VR so the 4080 doesn't really win on the RT/DLSS, then better be a whole lot better in raw performance

FWIW om using a 7900xtx With 5800x3d, 64gb ddr4 ram and a Pico 4.

the performance is outstanding. Previously I’ve had 3080, 6900xt, and it just doesn’t come close in comparison. Admittedly i haven’t tried a 4080, but I can’t imagine it comes close to 7900xtx in performance. I run pico 4 now on godlike in VDXR. All dcs settings to max, with 4x msaa, all shadows on, max draw distances etc etc. literally nothing dialed down. Recent small tweaks to dcs in updates seems to have made a lot of performance gains (for me at least). I also use QVFR. Game play is very smooth, looks amazing and I couldn’t be happier. Mostly I play dcs liberation campaigns so they are busy and lots going on.
