Performance problems with AMD Radeon RX Vega 64 models
Performance problems with AMD Radeon RX Vega 64 models
I own a Vega 64 GPU from Gigabyte, specifically the Radeon RX Vega 64 8GB OC Edition. It hasn’t been performing well since I acquired it in 2019, as I’ve mentioned before. Recently, my issues have intensified—my computer sometimes freezes, the screen goes black, and then it crashes unexpectedly. These problems occur even when I’m not doing heavy tasks like gaming or creating content (usually in UE4 or UE5). While my performance isn’t outstanding during those activities, I did some research after a crash and discovered that the error message pointed to "amdkmdag.sys," suggesting a GPU or driver issue. I don’t usually play many games, though I’m trying to improve. Recently, my friend suggested playing Fortnite, but my experience was disappointing. My FPS wasn’t bad, but frame drops were noticeable—sometimes dropping to single digits for brief moments. In contrast, Satisfactory runs well visually, except for occasional freezes during autosaves. The main trouble now comes when I work on game development in UE4 and especially UE5. My FPS fluctuates wildly, and the noise from my GPU is quite loud, so I often cap myself at 30 FPS to avoid stress. Recently, I tried running benchmarks (links provided). The numbers show: Gaming 53%, Desktop 89%, Workstation 51% with a GPU score of 54.3%. 3DMark results are 7028 for Gaming, 6930 for Desktop, and 3913 for Combined. The PCI Express test is concerning—my speed should be around 12GB/s according to PCIE 3.0 standards, but I’m seeing only 3.52GB/s. This is worrying. I’ve checked drivers, OS, BIOS, and everything seems up to date. I’m considering a new GPU or even rebuilding my system, but the market isn’t ideal right now. If there’s any way to resolve these problems—especially the GPU speed and stability—I’d appreciate it. My goal isn’t 4K at 120 FPS; I just need crashes to stop and smoother gameplay in UE5. Thanks for your help.
You're using Windows 10 Education Edition because it's designed for schools and educational institutions, offering features tailored to support learning environments.
Sadly, the situation isn't improving. I only have two desktops—one struggling with performance and the other that hasn’t been updated in a decade. It seems the GPU is likely the culprit, as benchmarks show it underperforms compared to similar units, and crash reports point to GPU or driver problems. Yep, that matches what I think. Just yesterday I played Fortnite with a friend again, and my FPS dropped from around 144 to nearly zero.
The crash seems linked to an AMD file, possibly due to a faulty driver. Have you attempted removing the driver using DDU and then reinstalling it? Your message didn't reference driver reinstallation, but I found others with the same problem resolved by updating or reinstalling drivers.
I performed a factory reset of my drivers using AMD's Radeon Software and then faced a significant issue with Windows 10 displaying a BSoD because the driver validation setting was active. I was able to enter safe boot mode and turn off that setting, allowing me to proceed with installing the new drivers. Since then, I haven't experienced any crashes (though performance remains subpar), but it's only been a few days. The problem hasn't been consistent. I'm uncertain if this is the same issue. P.S. Downloading the driver directly from Gigabyte's website opened up AMD Radeon Software for you.
