Okay but the point of the bench is to get an average of the game performance. So he got 90-100fps and with that the bench someone else posted was in the 90s. You ran settings for better performance with Ultra Performance setting instead and then claimed significantly higher FPS, well yeah course?

I think you don't understand the problem here.

He posted 2 benches, one with the 12900k one with the 7700x. We don't know what settings he was using and he didn't want to share. The 12900k was getting 90 fps while the 7700x was getting 110. So my point is, the ONLY way for a 12900k to get 90 fps in that game is to be GPU bound. Meaning, his 7700x would also be getting 90 fps with the same GPU. So I tested max settings with as low resolution as possible (DLSS ultra performance) to show that. If the 12900k can score 150 fps (like mine did) with max settings with DLSS Ultra performance, then it can also score 150 fps with DLSS quality assuming the gpu is fast enough to keep up.

Yes?

YES. Exactly, thats my point. Do you know how benchmarks work? What i tried to show with DLSS on ultra performance is that the 3090 is the bottleneck, not the CPU. If the problem was the 12900k, then I would be getting 90 fps no matter if DLSS was on or off or in quality or whatever.
We don't even know what settings the guy was using cause he didn't want to share so....

Right but the person playing their game with "assumed" same settings they use which is with DLSS on Quality is what that person was comparing too with the 7700x. You can't come in shouting my CPU gets more FPS so you are faking it if you are comparing different settings. What does your 12900k with DLSS on Quality get. If it drops to like 120fps or whatever we know that it has an affect on the FPS and in that particular scenario that one person happened to get more FPS out of the 7700x.

Man, ill ask again, do you understand how benchmarks work?

He was NOT using the same GPU for the runs. In both cases he was GPU bound, but he had a faster GPU in the 7700x. Resolution and DLSS make no difference to the CPU part.

I'm not sure what's confusing you.

Ignore the 7700x for a min.

Look at his 12900k vs 12900k results. The reason he's getting the same FPS is because he's GPU bound. That's why his mem and CPU OC on the 12900k show no gains.

Now for his 7700x (let's assume the game settings are the same), he's moved the GPU bottleneck significantly by going from a 3080 to a 3090. The comparison data is effectively useless.

So unsurprisingly you lost some FPS when going for higher quality. Yeah it still not 90fps. I am asking because I only have the data to read at face value. Has it been confirmed if the GPU is different cause then it would be a waste. But now we know you gain 8fps approx. then depending on DLSS Quality. And his is still 43fps adrift then?

Yes we need the full settings to see. I was just trying to actually compare data that can find that would be similar.

Okay I missed the data about a few things. I had only seen the one 12900k result vs the 7700x and had missed the 3080 to 3090. Yeah it a waste of time then. No worries.

I lost fps cause im still GPU bound. The 3090 is limiting performance. If i run at let's say 720p DLSS Performance, my CPU will get (let's just say for the sake of argument) 170 fps. So the CPU can achieve 170 fps in every resolution on every DLSS setting, even at 4 or 8k. It's then up to the GPU to keep up.

Well he never specified he changed GPUs, he is pretending he used the same rig with the same settings, that was the infuriating part.

Okay, well for the numbers to work you can get a 3090 at 1080p to get 90-100fps but not without cranking all the settings to max it would seem or actually being in game as per the video I linked. So it is technically plausible on same GPU but would have had different settings for RT and similar then I assume based on that. Fair enough.

I've tested a bit, and im pretty sure in the 7700x bench he is using a 3090 overclocked to hell at max settings + DLSS Q. I also get 110 fps with those settings if I oc my 3090. I assume, on the 12900k he is using the exact same settings but with a 3080 - or he powerlimited his 3090 to perform like that.

But yeah, anyways. At least you understand the issue ;)

No actually that's not how it works, you're only GPU bound if both CPU's get the same frame rates. because you're limited by how many frames the GPU can render.

If CPU A gets 90 FPS while CPU B gets 120 FPS then 90 FPS is not the limit of the GPU, its the limit of CPU A.
