Hi everyone, I'm currently using a ZOTAC GAMING GeForce RTX 3090 Trinity and an Aorus fv43u (4K 144Hz).

I don't know if I should upgrade to an RTX 5080 "right now" or wait for the RTX 5080 Super. The RTX 3090 rarely exceeds 4K 60Hz with the latest games (I only use the RTX 3090 when FSR 3.1 is available).

The only thing that puts me off the 5080 is the 16GB of VRAM (right now, it seems fine, but in a few years, it'll probably be a bit lacking). The 3090 also has 24GB of VRAM.

The rest of the rig is a Ryzen 79003XD with 64GB of 6000MHz RAM, an MSI X670E Carbon Wifi motherboard.

With these specs, would you be able to handle the RTX 3090 or upgrade to the RTX 5080? Or better yet, wait for the RTX 5080 Super.

Thanks
 
So I think that the most important question is, what are your primary applications for that setup?
Is there a particular game not hitting a desired frame rate, or do you do any GPU accelerated number crunching?

Since you mentioned FSR I'm taking that as a willingness to use up sampling, so the loss of VRAM might not be as pronounced in strictly gaming situations.

I think that it's acceptable if you want to keep the price under $2500 and are itching for an upgrade.

3090 is roughly equivalent to a 5070 right now, so even going to a 5080 is a bit of a letdown. The super series won’t really have much of a performance bump, only vram increase, and they’ve been delayed until late January so another 4 months. As other suggested would hold out until the 60 series or if in your budget get a used 5090 next year which would be a very noticeable performance implement.

Also any reason why you’re not using dlss4 transformer model for upscaling? It generally is much better than fsr3.1, to the point where a the internal resolution can be two to three levels lower for similar fidelity, which could gain you an extra 25% or so fps at minimum, much higher in other cases

4K gaming requires a 5090. My 2 cents which I am sure many people will come here and say no you are fine with a 4090/5080/5080 Super...

Hi, I'm using FSR 3.1. It's the only way to use Frame Generation with the RTX 3090. DLSS 4 isn't compatible with the RTX 3090. I can't use DLSS FG with my RTX 3090. Right? Did I miss something?

Frame Generation only works with the RTX 4000/5000.

Thanks.
 
The RTX 3090 does not support the new multi-frame generation feature exclusive to the 50 series, but you can get the core DLSS 4 on a 3090. You can still get improved image quality.

Find DLSS Override Model Presets and select "Latest" from the dropdown menu.

Never tried it myself, but it may offer something. Although I am giving it a whirl with a 4080 to see if there is any real benefit out of curiosity

You are correct Dlss4 frame generation doesn’t work on the 30 series, but dlss4 upscaling does. But as another asked, yes you want to get to 4k pixel count but what isn’t known is your target fps

If your target is 4k/60fps minimum you will probably get better image quality results by using dlss4 to upscale 1080p/60 to 4k/60 vs using fsr3.1 to upscale 1440p/40 to 4k/40 then frame gen to 4k/60.

Obviously numbers are just guesses above, but the process is similar.

Otherwise you can try to see if Optiscaler will let you use the Dlss4 upscaler while then using fsr4 frame gen, or even injecting fsr4 upscaling and frame gen into games and using it on the 3090

I gave that a whirl, didn't see much difference really. May try it later on a 3090 and take a gander
 
Now is probably the best time to get a 5090, another 1.5 years in its 'reign' and you can even find one's below msrp if you know where to look...

It's slower but looks better. I'm not 100% on transformer always being better than CNN, especially on a 30 series. Sometimes you have to upscale one notch more to hit your target fps using transformer.

The big difference is at higher upscaling ratios. I tried ultra performance in Cyberpunk since you can change models in-game and I was curious. The difference at ultra performance is huge. It goes from eye bleed to sorta tolerable. At DLSS quality I have a hard time telling which is which.

5090 is nice if you have the budget for it. We're already seeing games that are vram limited with 16GB, especially at 4k. Dropping $1k on a 16GB 5080 and immediately hitting vram limits would piss me off. I'd say either get the 5090 or wait for the 5080 Super.
 
The game that's driving me crazy is Chronos: The New Dawn.

I'm playing with FSR 3.1 and Frame Generation enabled.
I don't have FG with DLSS.

The only way to get FG is with FSR 3.1 (games that have it).

HellBlade 2 has FSR 3 but doesn't have FG, and I can't get 4K 60 fps.

I was able to play Gears of War Reload at 4K 120 fps with drops. It doesn't have frame generation or FSR 3.1.

My monitor is an Auros Fv43u (4K 144 Hz), so I'm happy with 4K 60 Hz for gaming.

Is there no multiframe generation mod for the RTX 3090? Not even FSR 4?

Wait and see if the 5080 Super is faster than the 4090. Your only upgrade path right now is a used 4090, a 5080 which is slower (don’t) or bite the bullet on a 5090. I’m in the same boat.

There is zero chance of that happening. Go look at a demanding game like Borderlands 4 and you see the 4090 is 30% faster than the 5080.

I'd go back and try DLSS. Also lower settings if you're trying to run maxed out settings. 4k maxed out in recent heavy games on a ~5yo 3090 isn't going to work. You have to lower settings or use a lot of upscaling. The best you can do with a 3090 is usually a mix of both. If you want to max out settings in recent, heavy games at 4k you need a 5090, and even that isn't quite perfect. Turn on full path tracing and you still don't have enough power to run 4k native and end up leaning on DLSS.

DLSS often performs better than FSR on NV cards. Not always, but it happens often enough that you should try it. Also DLSS 4 tends to look better than FSR3 with at least one notch more upscaling. NV cards have "tensor cores" that are used for DLSS. If you use FSR the regular shaders do all the upscaling, so upscaling competes with the rest of the game for resources and the tensor cores sit idle. It's the same with Intel cards. XeSS uses XMX cores for upscaling, but FSR again runs on regular shaders and leaves the XMX cores idle.

I'm not sure why you can't get to 60 in Hellblade 2. I don't have the game but I looked up TechPowerUp's performance review and they're getting 55fps at max settings on a 3090 at 1440p. Use some DLSS and/or lower settings and it should be easy to get to 60. Unfortunately all these performance reviews have a habit of only testing max settings. A lot of times "high" doesn't look much different from max, so there's no point to max settings if it kills your framerate. You just run what your hardware can do and if it annoys you enough you spend some $ and upgrade.

Chronos: The New Dawn at Epic settings may not be workable on a 3090 at 4k, but you should be able to get it running ok. It was getting ~35fps at 1440p native and 59 at 1080p using Epic settings in the performance test I looked at on a 3090. Once again the review people are only testing on max settings. Irritating. It's almost there at 1080p, and that's max settings. You always lose a bit upscaling so using DLSS performance 2x upscale to go from 1080p to 4k will be a little slower than 1080p native, but that 59fps was at max settings. So just lower settings a bit.

Finally, please stop trying to use framegen to get to 60. 60fps with 2x framegen lags like 30fps, actually slightly worse. You should be at 120fps minimum when using 2x framegen. With a 144Hz screen you have a pretty narrow window where framegen is actually good for anything. 144/2 = 72Hz. If you can go a good bit faster than 72 you're trading latency for visual smoothness. That's often a bad trade. Framegen is a lot more useful with a faster screen. Like if you had a 240Hz screen you could use 2x with a real framerate of 120 and get 240 displayed if your rig can handle it. That's pretty good for single player stuff.

Is the Rebar feature on the RTX 3090 worth it? Is there a performance boost? Or is it better to leave it disabled?
