FPS decreases simultaneously with reduced GPU and CPU usage
FPS decreases simultaneously with reduced GPU and CPU usage
I enjoy Destiny 2 and other titles for roughly five minutes before consistent frame drops start. Overwatch 2 runs smoothly at 240Hz, while the same game works perfectly at 144Hz. Destiny 2 maintains 150fps without any screen capture or video issues on Windows 10 Home 22H2 64-bit. My system specs include an AOC 25-inch 25G3ZM/BK monitor, ASRock B550M-HDV, Corsair Vengeance LPX, and a 2TB NVMe SSD. Power setup is a 700W 9PUE CM PSU with an AMD Ryzen 7 5800X (8 cores, 3.8GHz), RX 6700 XT (12GB GDDR6), and WD_BLACK SN850. BIOS version is P3.00. The video was created using Clipchamp.mp4.
It seems there might be a software problem, though this is unusual. Reinstalling the chipset drivers from AMD.com B550 could help. Make sure you’re using Balanced for the Windows Power Plan. Consider using a different power source, even if you have a UPS. Your GPU drivers appear to be outdated, as shown in Task Manager.
You can check disk performance in Task Manager (if missing) by running "diskperf -Y" in an admin prompt and then restarting Task Manager. I’m interested in seeing if any disks are heavily used together with CPU and GPU drops. Agall recommends updating video drivers and performing a full PC reboot, given your 18-day uptime.
Execute Cinebench R23 with the advanced mode for one test. Be aware that your motherboard can handle the 5800X, though it might not be ideal. The setup uses a 4-pin EPS connector, which likely restricts TDP or VRM performance. You may want to enable this setting in UEFI to check if your CPU attempts higher boosts than expected. It's also possible your storage is overheating, especially with the PCIe 4.0 slot beneath the GPU. Running HWinfo64 in the background could help monitor CPU power usage and drive temperatures.
Sorry to clarify, but I’m still getting the point you’re asking about. The reference seems to be checking if your CPU is attempting an unusually high boost in UEFI settings. The temperature reading of around 50°C during Destiny 2 suggests it was running hot, which could affect performance or stability.
The 5800x aims for more than 140W, yet the board caps around 105W. Setting TDP to 105W via ECO mode in UEFI might be worth testing. It’s also conceivable your RTX 4080 is drawing too much from the PCIe bus, a detail HWinfo64 can reveal in the GPU power dropdown. The reported 9885 watts is unusually low compared to typical benchmarks like Cinebench R23 (around 15k). The single-core performance aligns with a normal 5800x, though a 105W limit should support at least 12k. Regarding RAM, your Ryzen 5000 should follow a 1:1:1 FCLK:MCLK:UCLK ratio, which governs the bus between CPU dies and memory controllers. With a 3600MHz RAM module, expect around 1800MHz on FCLK:MCLK:UCLK. Most processors support it, but your motherboard may struggle. Adjusting RAM to 1600MHz and keeping it in AUTO mode should enforce the correct frequency.
The system power unit is quite poor and not suitable for this setup. As discussed before, make sure all your drivers, chipset, and BIOS are up to date.
