[SOLVED] RTX 3090 low fps? bottleneck?

[MasterMatt7]

Hi guys. Haven't posted on here much but this community is always very helpful. I just got an RTX 3090 and the performance I'm getting is nowhere near the benchmarks I'm seeing online. I just upgraded from a 1080 TI and I'm only getting about 10fps better on average with the 3090. I just ran a shadow of the tomb raider benchmark on high at 1440p and got an average fps of 101. Multiple sources online are showing 170fps for this. COD Warzone on high settings at 1440p I'm averaging around 100fps and I'm seeing avgs of 160fps from users online. Here are my full specs:

MB: Maximus IX Hero
GPU: RTX 3090 FE
CPU: I9 9900k
Lian Li Galahad 360 cooler
Samsung 960 EVO 500GB
Corsair Vengeance LPX 32GB DDR4 RAM
EVGA supernova 1000 g3 gold PSU
ASUS ROG PG279Q

I just upgraded to the latest nvidia drivers. Temps look fine. As a test I switched back in the 1080ti and got 91fps in the tomb raider benchmark, 9fps lower than what I got with the 3090. Any thoughts here? I'm contemplating doing a clean install of windows.

The performance drop you're seeing doesn't seem to square with the hardware you are using as I'm not seeing any one thing wrong with your hardware that should lead to such a large drop in performance compared to what you have seen elsewhere. We all know that no one will ever get the exact same results with different hardware, but there is a very large difference here indeed.

Two things stick out to me as possibilities: your CPU and your RAM. What speed does your RAM operate at? 2666 MHz? If so, that might be (part of) the problem. At the very least it is probably making the gap wider than it would be otherwise. And then there's your 9900k; is it overclocked? Both Shadow of the Tomb Raider and Warzone are heavy on the CPU (probably very heavy at the frame rates you are looking for) and not overclocking it to 5.0 GHz on all 8 cores is leaving fps on the table.

Thanks for the quick response. Just checked, you're right on both accounts. My ram is at 2666 MHZ and my 9900K is completely stock, not overclocked.

I think you and I have the same RAM; I was able to go into my motherboard BIOS software and overclock it (using XPM profiles) to 3000 MHz. How many sticks of RAM do you have? I'm assuming at least two right? If so, good, you are using dual-channel (very important).

Well its no wonder you are getting lower fps with a stock 9900k; all those benchmarks you are seeing are using the latest and greatest CPUs all overclocked as high as they can go. CPU clock cycles directly affect your fps, so by running at stock clocks, you are giving yourself an unnecessary CPU bottleneck.

It is very common to see people able to overclock a 9900k to 5.0 GHz on all 8 cores (provided there is adequate CPU cooling of course; the 9900k runs really hot). Seeing as how you have a 360 mm AIO CPU cooler, this should be no problem for you whatsoever.

I'll add that when trying to run shadow of the tomb raider the first time i got this

"A problem has occurred with your display driver. Your system may not have enough resources to run the game at the selected settings. You can retry using the same settings or adjust them to lower settings. Make sure you have the latest drivers for your video hardware, and try rebooting your system to help clear up any issues.

I got it a second time, a reboot fixed but it seems odd.

Hm, don't know what to make of that.

Try overclocking your RAM and CPU, then let me know what your fps gain is.

Thanks ! Will report back in the am.

Thanks ! Will report back in the am.

By the way, congrats on the new 3090; you are the envy of everyone on this forum right now lol.

Since you have a 9900k, i recommend overclocking to 5ghz, its extremely beneficial and easy to do.

I kind of covered that already; just in case you didn't read through the thread, here you go.

To quote myself:

Can you run userbenchmark and post a link to the results.

I would hold off overclocking. Your performance seems too low even for stock settings.on COD MW I’m running a 3080 with 3700X at 1440p and with max settings and RT on I’m averaging 130+ FPS. Overclocking when there seems to be a problem already is just going to make it harder to diagnose the problem.

Have you tried removing the driver using DDU and the reinstalling?

 

[MasterMatt7]

Hi guys, thanks for all the responses. So I removed the driver using DDU (removed everything nvidia related in the program), then redownloaded the latest from nvidia. I got 117fps on the tomb raider benchmark immediately after doing that (vs 101 originally). Then I overclocked the i9 9900k to 5.1ghz (all cores). Reran the tomb raider benchmark. Got 147fps. Definitely a big bump over before. I have not overclocked the ram. Does this sound like reasonable fps for a 3090 and i9 9900k? Odd that the gamers nexus video is showing 170fps but I get there could be some differences (he also has 3200mhz on ram and the 10700k .

I posted the wrong MB before, I have the Maximus XI Hero, don't think that is relevant though. I'm reinstalling warzone to see how it runs now. Let me know what you guys think.

Definitely a solid improvement, I'm happy to see that you're getting better results.

Yeah, the faster RAM and the different CPU/motherboard combination are probably where the missing fps are. The problem with using a card like the 3090 to game at 1440p is that to make full use of it, all the supporting components need to be much more powerful than they would need to be to extract maximum performance out of a game at 4k. Thus, stuff like overclocking your CPU, your RAM frequency and other small things that normally wouldn't make much difference at 4k need to be pushed to the limit.

Even with better RAM, you still probably won't see as high as fps as gamers nexus did. They are also using a 8 core / 16 thread CPU from Intel, but the Comet lake part they are using is on a different motherboard, plugged into a different CPU socket with more pins and a more robust power delivery subsystem.
