RTX 4070 ti for VR in DCS (?)


Tom Kazansky

Recommended Posts

For high res VR it's not ideal, it's memory bandwidth is a little over half that of a 3080ti and can't push enough data through fast enough. Stay with lower textures and resolution and you'll be ok. Rift S or index and you'll be ok, Q2 or above and I think you'll be suffering a bit.

Even the 4080 is less bandwidth than the 3080ti although it is a faster card. I'm not sure what the direct comparisons are like for DCS VR though.

edit: first review I find for the 4070ti states that is worthless for 4k due to memory bus, the G2 at default resolution is pushing almost 2.5 times the number of pixels than 4k!

Hi!

Is the EVGA GeForce RTX 3090 FTW3 Ultra Gaming still the best graphics card for DCS VR in 2023?

I have an I9 12900KF processor on a WIFI PRO Z790-A motherboard with 32GB RAM running with my old water cooled GTX 1080 TI GPU.
I was wondering which GPU would be effective in VR for DCS without being a budget killer.

From the last generation yes, only the ti is slightly faster.  From the current generation I'd only go for the 4090 if budget allowed as it gives a sizeable uplift, I don't know that the 4080 is any faster than a 3090 in VR.

I'm sure the new RTX 4070 ti is good for DCS in 2D even at 4k.

With this thread I want to ask people about their experiences with it in VR.

Does it make sense or is the 4080 that much better to be worth that higher price tag?

According to some posts on Reddit, (non DCS) VR performance is similar to 3080.  This may change when DCS has DLSS mode since current gen cards have better tensor tech but as of now think of it as 3080 equivalent in VR.

That wouldn't be bad for the money and power consumption of the 4070 ti.

A lot of people think it's too expensive for what it offers, but in this era where a lousy half-inch Subway sandwich costs $8.50 (without tax) it seems about right to me--if you can get it at MSRP that is.

FYI, DLSS doesn't support VR. NIS might, but it's much less of a deal. FSR is a mere possibility right now.

Thanks for the info. I missed FSR in the recently posted to do list for DCS in 2023 though. Is there any sign for hope that I missed?

I should have added "compared to the 3080". I do agree in general and have only little to none hope that we could get close to good old times again.

They mentioned it'll be looked into after DLSS implementation is complete. So, not anytime soon.

You can have NIS or FSR as well as CAS right now via fholger’s VR perf kit mod.

Bear in mind that the 3080 still has about 50% more bandwidth than the 4070ti, it's going to bog down with the amount of resolution and texture it has to push through currently.

Analogous to 1000 cars travelling from point A to point B, put them on a 4 lane motorway that can do 70mph and they will get there quicker than on a single carriageway at 50mph.

Why in the world would they use 2.0 when we have 2.5.1 right now and it’s working incredibly well with other VR games?
