Performance issues with GPU at 4K resolution...
I've begun aligning my FPS numbers with what reviewers report after getting my 6800XT. It appears I consistently fall about 15-20% short, particularly during dips in minimum frames. Now I'm playing these titles at 4K resolution on an LG C9, yet for some unexplained reason my CPU seems to limit the GPU performance... even at 4K! I've completed most of the testing possible. While gaming, my 10700k reaches around 72°C with the Hyper 212 Black Edition cooler (acknowledging it's not ideal, but I run it stock). That shouldn't indicate throttling problems. Prime95 FFT results show extreme heat spikes to 95-100°C (definitely a throttle point), though those aren't typical for regular gaming. At 4K resolution, I expect no CPU bottleneck, especially not at that level. I've attached a screenshot of my setup and two benchmarks—one from Gears 5 and another from Assassin's Creed Oddyssey. In the latter, you'll notice the minimal frame drops line up with CPU spikes. Any guidance would be invaluable; I'm really struggling here and need help!
When nothing is open, CPU usage might be high. Check the task manager, order by CPU, and observe what’s consuming power. Temperatures from Prime95 shouldn’t spike much, even with a Hyper 212 and 10700K. Verify the cooler installation and ensure thermal paste is applied properly (or replace it if you removed the cooler and have spare).
CPU activity remains minimal at just 3% during idle time in the Task Manager on Windows. I replaced the cooler, reapplied thermal paste, and verified proper installation yesterday, which suggests the problem isn’t resolved.
Sure thing. I’ll set up MSI Afterburner and activate those overlays as requested. Once done, run a game for over 15 minutes and let me know the results or share an image. Please let me know when you’d like me to notify you, by clicking the arrow in my comment.
AC:O remains a CPU game still reliant on GPU power at 1080p. It performs well even when overclocked to 4k. My i9 9900K is near the capabilities of your CPU, but I rely on Nvidia GPUs. The closest models I’ve tried are a 3080, which handled 64 frames smoothly—so there might be an issue with your setup. Check if your CPU and GPU are working together efficiently and whether RAM is affecting speed. I usually use Time Spy for this because it provides detailed online data.
Here you are, for an unexplained reason I couldn't pick the main thread 15, though everything seems fine otherwise.
Reviewing others isn't a reliable method for assessing your performance unless you understand their exact configurations, testing locations, and settings. Most reviewers don’t share detailed information about the environments they used. I think Gamers Nexus does provide this data, but others often omit specifics or rely on limited benchmarks. Many skip broad tests and focus on certain game areas instead. From the Afterburner stats image you shared, your performance is heavily constrained by the GPU, with no cores fully utilized—this matches what you’d expect at 4K resolution.
I detected 99% GPU utilization, which aligns with expectations. Exceeding 90% indicates efficient resource use and no major constraints.
I swapped my CPU and motherboard for a 5600X since I felt the CPU was limiting performance. Outcome: the CPU bottleneck in Gears 5 vanished completely (as expected at 4K), achieving much better low-end performance. Unigine scores are now closer to what reviewers say, with roughly a 25% improvement in averages and 50% higher minimums. I still don’t understand why the 10700k was struggling at 4K, but it definitely was.
