5090 v 4090 VR

[C3PO]

I guess DCS would still be CPU limited even with the 4090 and 9800X3D ... so is the 5090 really worth it in VR with a Crystal Super?

I'm CPU limited with a 4090 and 14900KS, I can't see a 5090 having anything other than a negative impact on my bank balance in the context of DCS.

[Panzerlang]

Nope, not for DCS. I intend to down-sample my Super, because there sure isn't any benefit to be had by chucking more pixels (5090 for a Super at native res) into the already maxed-out Render Thread of my 13900k.

IL2, however, will see a huge benefit from a 5090, down sampled Super, so yep. Lol.

so... I will hopefully today or tomorrow upgrade to a 9800X3d depending on my cooler arrival. so i will let you know if i still CPU bottle neck... my own feeling on the 5090 is we just don't have enough data to make any informed choice yet, but for me its certainly not an "auto buy" I would like to get real world rasterization numbers before i even consider it ... my normal habit is to upgrade over 4 years for my CPU and GPU and offset that so CPU then GPU  ( 2 years apart) I'm in my CPU cycle now... si I am not "due" for at least another 2 years.

If DCS picks up the technologies provided in the RTX5x series of cards that might change, but, that doesn't seem like an immediately likely outcome ... and even less so for a VR player

With Q3 1.3PD, VD AV1 using Godlike preset locked at 72 Hz I'm am CPU limited sometimes, roughly 40:60 Cpu: GPU limited. I'm on a 4090 and 9800X3D overclocked to 5.6Ghz.

With Super and 5090, assuming you're not playing at potato graphics settings, i can't see how you would be CPU limited. Pushing that high a resolution, with quality graphics settings at 72/90 FPS even the 5090 is going to be your limiting favtor.

Now whether it's worth it or not, that would be your decision to make based on your current hardware, your financial wellbeing, and what you consider to be an acceptable level of quality/performance of gameplay.

Be very interested to hear of any uplift in performance you get as a result of the 9800X3D

yeah , I mostly "hoping" for an improvement in AI busy scenarios and airfields/strike areas as that where i tend to see CPU encroachment also has i made the move to a 12700k but on DDR4 and my older m.2 drive i should get several "improvements" from that as well ... we will see...

I am almost never GPU limited at the moment, but we shall see if not at least I will be on a hardware platform that wont need replacing every couple of years

If your 4090 is underutilized, crank those GFX settings up. Most of the time my 4090 is 98-100% utilization and that's just with a Q3. Which sometimes kicks me into re-projection; it's fairly rare bit does happen.

Or the render resolution.

The cost increase quoted there in the HUB video is a bit mistaken. In today’s dollars the $1,599 RTX 4090 is $1,693.40 for an actual cost increase of $1,999/$1,693.40=1.18 so 18% not 25%. Every penny counts

[nephilimborn]

tangential to this topic; however i found this buildzoid vid interesting as it relates to both - still no shunt resistors on the 12V HP connector

Meanwhile this is exactly what the thread is about. 

 

 

Too bad prices are going up with some of the partner cards. 

[Ready]

I don't see my rig getting the same improvements as in this video, will hold out for more data.

Found another thread locked.

Thinking of upgrading to the 5090, from 4090. The thing is, the used price for 4090 is insane today, making the delta after selling the 4090 and getting a 5090 taste quite good. 
I get the ~15% performance difference.

 

Someone wrote in a locked theead about having issues to get the 5090 to run with certain VR-sets ( I use Varjo Aero).

Is these issues still present, anyone?

One user posted this on Varjo Discord with regards to the Aero.

I installed my MSI 5090 a few days ago and was having the low FPS and stuttering that everyone else is seeing.  While troubleshooting an intermittent Aero video problem, I upgraded VB from 4.5 to 4.7.  I was still having no video on the Aero.  It would work when I first started VB, but the video would go away after a couple of seconds.  VB said to uninstall VB and reinstall, so I did that.  After the reinstall of VB 4.7, everything works perfectly.  The stutter is gone.  I have all of the graphics settings set as high as they go in both LMU and AMS2 and both are locked on 90FPS with GPU headroom to spare.

Wow - the definitive comparison ismaeljorda, thank you.

So compared to what I have got with my current system, my FPS in VR would nearly double.

[Dogmanbird]

here in aus the 5090 is more than double the cost of what the 4090 sold at, for 30% improvement. australia's gone totally totally nuts

but for $1000 aud more, you can buy a complete 5090 gaming PC (probably with the cheapest additional components)

Coming from a 4090 im gonna skip a gen. 6090 it is unless the price is just as crazy as the current gen.

Im not gonna burn my money on the GPU mafia at this moment.
