Lower FPS on 4080 than expected

Hi everyone! So I recently upgraded from a 2060 to an MSI 4080 Gaming X Trio. I was aiming to game at 1080p and I was aware before buying it that my CPU (i9-9900k) would bottleneck the most at that resolution. I did some research prior to getting the card and was seeing that I would probably get a 10%-15% decrease in performance. But after seeing a ton of benchmarks of games at 1080p, I'm getting almost half the frames from all of the benchmarks in games like Cyberpunk, RDR2, etc. All settings on high-ultra in RDR2 are at 75-80 fps and Cyberpunk is the exact same frames. I put all the settings on low in Warzone 2.0 and I'm only getting 90 frames. Even turning on DLSS barely helps. I also have the latest NVIDIA drivers installed and my refresh rate is at 240Hz on Nvidia Control Panel. I'm really hoping I am just overlooking something simple, but I don't know what else to do. Any help is appreciated!

Honestly speaking, buying a 4080 to play at 1080p was pretty dumb to do. Its gonna have some major issues.

 

Generally you need to do a complete Display driver removal (DDR) and once you cleanly wiped it try again. 

 

Also playing on ultra high with certain settings will always limit your FPS. Some of those settings are pretty trash for performance

Definitely CPU bottleneck, 9900k is barely faster than 12400, in gaming 12400 would beat it. I happen to have 12400, it sometimes bottleneck my 6800 XT in 1440p, imagine a 9900k with 4080 in 1080p...

I'd say, you'd need 13700k or 13600k to maximize 4080 in 1080p.

4080 is a 4K card anyway, if you plan to play in 1080p or 1440p, go with AMD, their GPUs are somehow better in lower resolution but worse in 4K.

Yeah I was aware before buying it that it isn't a 1080p card. I wanted an upgrade and had the opportunity to purchase one. 

 

And I'll do the DDR right now. I'll let you know if that helps. Thanks!

 

Are there any settings in particular that are not worth the performance decrease?

Should be able to use Display driver uninstaller for it.

 

Generally it comes down to what you are okay with losing out, and every game is gonna be different sadly. So its hard to say what settings, id recommend looking into each game and see what other post about it.

okay great!

 

And one last question. So for a CPU bottleneck to occur, it should be around 98-99% usage. But my CPU hovers around 75% and I don't have a frame limiter. Why do you think that may be happening?

 

I even lowered the settings in the same games to all medium and getting the same frame rates.

Lowering settings will make your cpu work even harder. in most games if your cpu is at 75% it is maxed out since you arent using every core. try raising your settings to lift the work off the cpu a bit , if you use afterburner you will want to see your gpu usage around 98-99% and cpu usage go down

[Dukesilver27-]

Because the games wont ever use all the cores, theres no way it would reach 100% usage. Just because the usage is not 100%, doesnt mean that the CPU is doing fine. 

Games rarely use more than 4 mores, only very recent games start to use more than 4 more cores. So you'll see that 2 or 4 of the CPU cores usage are much higher than the rest. 

Games favor single core performance due to this, by today's standard 9900k is weak, even a 12100f has faster single core performance. 

I guarantee you that without an upgrade or rendering the game in 4K or more, bottleneck would always be there.

Okay good to know! When was playing RDR2 on maxed settings, I saw that my core load for all 8 cores were using 57-73% It was the same situation for Cyberpunk. Does that not mean all of the cores are being used for the game?

i don't really agree... i love playing with DSR, so 1080p technically wouldn't be 1080p, and if 1080p was an issue everyone could to that... problem solved!?

 

ps: i strongly believe op has a cpu bottleneck,  regardless of resolution... don't most cpus bottleneck a 4080 anyway? 

 

 

[Dukesilver27-]

Yes they are, but not spread evenly, which is an issue for all games, the engine can't spread the workload evenly across all cores, which hinders performance. Also, the CPU's cache size affects performance as well.

Anyway, RDR2 is a pretty well optimized game, if your GPU can't reach 100% utilization, the CPU is the issue.

You can try OCing it, but I doubt the performance would increase much, maybe 1-3%.

4080 is faster than even 3090 Ti, people get bottleneck on 3080s in 1080p, even with 12th gen CPUs.

Trust me or don't, my opinion still is that the CPU is bottlenecking the GPU.

[Fendrick]

Just to step in here and clear some of the nonsense in here.

 

Bottleneck or no bottleneck, a CPU will give only X amounts of frames regardless if the GPU is under utilized or is the bottleneck.

what I am thinking is that the OP changed from an RTX 2060 to a 4080 and their performance is now half of the 2060, that is exactly how the OP typed it.

So if the CPU is the bottleneck then it should be gving the same frames it did with the RTX 2060 in CPU bound scenario's.

 

There is an issue elsewhere.

So I am also having issues with lower than expected FPS with my new build. I thought I would easily get 200+ FPS on 1080p/144hz in Warzone 2. But I am only averaging about 160. What gives? Some say I am bottlenecking cause of my RAM, but I can't find a true consensus.
