Your RTX 4090 setup isn't delivering the performance you expect.
Hey everyone, I’m a bit puzzled about how my gaming setup is performing lately. I recently swapped out my GPU for the RTX 4090, replacing the GTX 970. You can find my configuration below. WINNER: 10 64bit 22H2 SMBIOSBIOS Version: 3602 MB: ASUS ROG STRIX X570-E GAMING SSD: Samsung SSD 990 PRO, M.2 - 2TB (or unsure about the 980 size) GPU: Inno3D GeForce RTX 4090 iChill X3 24G CPU: AMD Ryzen 9 5900X Cooler: Noctua NH-D15S RAM: Patriot Viper 4 Blackout Series 64GB KIT DDR4 3600MHz CL18 Case: NZXT Phantom 530 black PSU: MSI MPG A850GF Monitor: Philips Momentum 279M1RV 4K My first game was Horizon Zero Dawn – everything ran smoothly at max settings, whether on a 1080p or 4K screen. I’m also a big fan of Rocket League; by default it suggested 360fps and it worked well. Later, I tried High Life and Hogwarts Legacy, but both suffered from stuttering, which seems common for many PC users. I removed the problematic game for now and installed Shadow of Tomb Raider – it didn’t run perfectly, but it was an attempt. Regarding Rocket League, even with updated drivers, it still only reached 144fps and wasn’t very smooth at times. After reinstalling drivers and Windows, things improved slightly. I’m wondering if there are any tests or apps you’d suggest to check performance more thoroughly (to share results). I’m also curious about the PSU wattage – maybe it’s not enough? But honestly, the specs look sufficient for an NVidia chip, and it never crashed before. Could you point out any problems in my build? Perhaps the PSU isn’t delivering enough power? I’d appreciate any tips or tools that could help diagnose what’s going on. Thanks for your help – I hope this gives you a clearer picture!
Your Ryzen 9 5900X presents a significant limitation with a 4090. Back then, a 9900K at 5.1GHz matched its performance, but paired with an RTX 4080 it became nearly impossible to play. Most games suffered from stutters, lower frame rates than expected, and an overall poor experience. Switching to a 7700X improved things, boosting FPS by over 30% and eliminating the minor lag entirely.
Do you find this convincing? It's clear the load I experienced never exceeded 15%-20% on any core. Plus, back then you could reach 5950x, which makes it seem like a premium option. Yes, that definitely feels like a high-end choice.
Are you achieving the best performance from the 4090 paired with a 5900X across all resolutions? Not really. It shouldn’t be choppy. Your CPU temperatures are stable? Check out the 4K outcomes in this clip.
It's no longer seen as top-tier, though it might be mid or high depending on the GPU you're using. CPU usage alone isn't the full picture when it comes to bottlenecks. IPC (instructions per cycle) plays a big role in how fast the CPU works. My 9900k ran at 20-30% but still wasn't quick enough. It's hard to put into simple terms, or at least I'm not sure how to explain it clearly.
Confirm the latest BIOS for your motherboard, then verify all settings are correct. Use DDU to reinstall the newest Nvidia driver and ensure the most recent AMD chipset driver is applied. Note: The chipset driver should come from amd.com, not Asus.
I need to keep this in mind whenever I’m handling hardware sales commissions versus performing diagnostics or troubleshooting.
