Is there an issue or a constraint in progress?
I recently purchased a new PC and noticed frequent frame drops while gaming. Initially, I suspected a Windows 11 issue or another problem, but now I suspect the CPU is limiting performance. The I9-11900K and your specs (3090 TI I7-11700K, 32GB RAM, 3600MHz) should handle the workload. It might be worth upgrading for better stability.
It shouldn't be a bottleneck that leads to frame chokes except possibly at low/very low resolutions. The specific games, settings, and resolution levels causing the drops are unclear. Overall frame rates drop significantly, but CPU and GPU temperatures appear normal.
Played both Dead by Daylight and Fortnite. In Dead by Daylight I used 1920x1080 with low settings and noticed steady drops from 120 to 100, which isn’t huge but bothersome. In Fortnite I played at 1720x1080 on all low settings and experienced random drops from 240 down to around 100, sometimes even into double digits. With my older PC—a 2070 Super and i7-10700K—I consistently got 200-240 with no spikes or drops. My GPU temperature stayed around 50-60 while using only about 20% of the processor. I’ve made many optimizations and tried different things, but nothing seems to have resolved the issue. I’m unsure if a better CPU is needed or if there’s something else missing, but any advice would be greatly appreciated.
It seems the CPU is struggling relative to the GPU. This happens because the CPU handles both its own operations and sends tasks to the GPU, affecting RAM usage. When it slows down, you often notice stuttering since the whole system waits for the CPU. I’m not sure if a CPU can handle a 3090 Ti at 1080p low; a 12900K might be better, but even then it’s more about testing PCIe speeds than actual frame rates. You might need to raise graphics settings, lower resolution, or avoid using a 3090 Ti for 1080p low.
Something is definitely wrong, but more importantly, why do you have a 2000 dollar PC to play at ancient resolution and low settings..? Did you build it yourself? BIOS updated? Temps all look ok? RAM working in dual channel?
I completely understand, but using that machine for 1080p low settings isn’t a smart way to invest your money. It wouldn’t cause performance issues; it would likely hit the CPU limit quickly, but still maintain hundreds of FPS. There’s something off here that needs clarification. Still, I agree. The player should invest in a proper monitor instead of relying on low settings for 1080p gaming. A 2060 and an i5-8600 would be a solid choice for that resolution.
The CPU and GPU temperatures during stress tests and in games remain consistent. Dual sticks of RAM operate correctly in dual-channel mode. No overclocking is present.
Consider playing the games in 1440p or 4K using Nvidia's DSR. The 3080 struggles at 1080p, so a 3090 on a 1080p screen might not be much better. I think you're making a poor decision, especially with the 3090 Ti on a 1080p monitor. It's smart to research before purchasing, as you'd already know this limitation.
