Is RTX 4080 good enough for Reverb G2? No prior VR experience.

[p6889k]

I have zero experience with VR. Just purchased Reverb G2 on the black friday sale, so am super excited to finally get into VR. Was also planning on upgrading my GPU to RTX 4080, just waiting for stocks to replenish. Currently gaming on 32" 4K 2D display with TrackIR, i7-12700, 64GB DDR4 RAM (at 2133MHz, 4 RAM sticks unstable at 3200MHz), GTX 1080, VKB Gunfighter, MFG Crosswinds . Mostly play IL-2, dabble little bit into DCS and MSFS, but not much.

 

Will RTX 4080 be good enough to have a great VR experience with the Reverb G2 in IL-2 or should I push for RTX 4090?

 

I don't know how to quantify "good enough", my guess is stable 90fps, full resolution ?

 

What would RTX 4090 give me over RTX4080?

 

Again, I have zero previous experience with VR so have no idea what to expect.

 

I do suffer from motion sickness in general, so I guess the smoother the playback the better? Flying without TrackIR induces motion sickness for me, with TrackIR I have no problem if I stay under 2.5 hour playtime, after that I start feeling it a little.

 

I would hate to buy 4080 and end up right below some optimum performance if only I went for 4090. At the same time these GPUs are expensive so don't want to spend it if I don't need to.

 

CPU wise, i can overclock my i7-12700 quiet a bit if needed. I could also upgrade to 13th gen if really needed or maybe even Zen4 3D whenever it comes out. For now I'm hoping 12700 with some overclock should do for another year?

 

Thank you.

4080 will be fine, even a 3080 runs IL-2 pretty good and the rest of your system is no slouch. But yeah that 1080 is your weak point.

Welcome to VR!

As Dburne said, a 4080 is already more than enough for the G2. And that card will also more than enough for future VR headsets in the next years.

In fact a 3080 will be also quite OK, but with the 4080 you will have a longer usage for future resolutions.

 

You can run the SYN_Vander bench before and after your GPU upgrade, so you will see the difference.

Not a VR guy, but wouldn't 2133mhz ram speed be a bit slow for optimal 90fps performance?

Another option is to get a 3090 and use the savings to upgrade your ram to 3600MHz 32Gb (2x16).
 

Barring that, I think 4080 should be enough. but, if it comes between buying an AIB 4080 to FE4090, I’d definitely choose the FE4090 since the price difference is about $150-200 between an AIB 4080 and FE 4090.  
 

about motion sickness; take it slow (15-20 minutes tops, a session) stop as soon as you start feeling nauseated, take a break and go back again if you feel like it. I can’t stress this enough! Do NOT try and force the nausea, just take a break. No game play either. Just hop in a plane in testing mode with no other planes, start in air the first several days, try taking off from runway afterwards. 
 

slowly increase your play time and over a period of 7-10 days, you will, hopefully, get fully acclimated. It took me about a week, and driving sims actually affected me much worse than flying. 
 

It’s been recommended bass shakers help immensely with motion sickness, but I didn’t have a setup and was fully acclimated in about a week. Good luck, you’ll like it a lot if I was to make a guess.

It is quite low in fact. It has an impact in VR. 

64Gb is way too much RAM, it is better to have just 32Gb but faster (and for IL-2 even 16Gb an even faster)

What's the connection between RAM speed and VR at 90fps? Is there some combination of minimum speed, latency, timings.  Need 64GB for video and photo editing so going down to 32 GB is not an option, and I'd rather not buy new RAM at this point, will want to wait until I move to DDR5 platform and then maybe try 2x32GB.

 

Attached is a snapshot of the speeds/timings supported. It used to run stable on X299 platform at 3200MHz, on Z690 it's unstable, so running at default 2133Mhz, which has been fine as I didn't notice any performance difference in any of the applications or games. So am puzzled why it would make big difference for VR?

OK, I see, if you need 64Gb for other apps then it has to be 64Gb.

 

RAM speed&latency has an impact in the test we did along the years with several IL-2 benchmarks, you can take a look at the SYN_vander table and other previous tests.

The impact is not huge but measurable. It could be about 1 fps for every 100MHz but it depends on many factors and limits.

Your lower speed 2066 has a CAS of 14 which is better than the CAS of 16 of your XMP profile at 3200MHz.

 

I have seen that Z690 models are not in the QVL of Gskill: https://www.gskill.com/qvl/165/184/1535687484/F4-3200C16S-16GVK-QVL

 

What is the model of your Mobo? is your CPU the 12700 or 12700K?

MB: MSI PRO Z690-A DDR4

CPU: 12700K

 

I've tried all sorts of manual RAM configs to get it stable at 3200MHz, but it wasn't stable. Following various message boards it seems that the moment you go to 4 sticks the Z690 chipset can't handle XMP speeds. I was on HEDT chipsets for a while and those worked just fine with 4 sticks and XMP.

This was wrong.

Your RAM appears in the QVL of GSkill in mode 4x16Gb. I would contact either support of Gskill or MSI.

I play IL2 online, and for some reason my ram gets really hot at times. My ddr5 is active cooled as well. Most of my other games don't even come close. Does IL2 utilize ram more then others?

In the past I was only looking to the amount of RAM (look here) , but not about about intensively is used or RAM temps.

I suposse that higher freqs will produce more heat, but this should affect all games equally.

It is perhaps the physics base model of IL-2 what require more intensive usage of RAM. But I have no idea.

Good news about my 4x16GB configuration, looks like MSI just released a new motherboard BIOS with improvements for memory compatibility and with this new BIOS my DDR4 RAM is running stable at 3200MHz instead of the default 2133MHz.

 

Back to the original post topic, sounds like RTX4080 is a good match for IL-2 and Reverb G2. So what benefit if any would RTX 4090 bring?

You will have a cpu bottleneck with either a 4080 or 4090. But you will be able to add more msaa and other higher visual settings in IL2 for VR. The main differences are better explained in the babeltech review..

Nice.

About the 4080vs4090 for IL-2 VR with G2.  With the 4080 you are weeeeeeeell above what the G2 can deliver.

 

I think that going to the 4090 could be considered if you want to upgrade your G2 for an Aero or Crystal or whatever Valve will release next year.

Thanks, that's the kind of feedback I was looking for. I don't think i'll be upgrading VR headset anytime soon, will want to get good 2+ years out of it. So my next VR upgrade will probably be around the time 5000 series RTX comes out.
