Fixed Vega 56 Issues
Fixed Vega 56 Issues
I recently switched from a Radeon RX 580 to a Gigabyte Vega 56 OC and anticipated a significant performance improvement, particularly at my 1080p resolution. However, I observed a decrease in gaming performance. This wasn’t evident during benchmark tests; on 3DMark Time Spy, I achieved approximately 6800 points – consistent with results from other systems with similar specifications, and a UserBenchmark score of 92% after utilizing Wattman for undervolting and overclocking.
Despite this, I encountered difficulties reaching 60 frames per second on medium settings in *Batman: Arkham Knight* and *Kingdom Come: Deliverance*, experiencing lower frame rates than previously achieved. I performed a clean driver installation from Gigabyte’s website using DDU, but the performance didn't improve. Updating the BIOS to the latest version also failed to resolve the issue, nor did reinstalling the latest drivers from AMD. I attempted undervolting and further overclocking as described earlier without any change in performance.
I verified that the GPU wasn’t overheating using HWMonitor and my own observations, finding temperatures consistently around 40-50 degrees Celsius. Notably, *Kingdom Come: Deliverance* heavily utilized the CPU at approximately 75% utilization while graphics usage remained below 60%. Consequently, the core clocks were fixed at roughly 1100MHz and 700MHz for the HBM2, which I believe is also true for other games I've tested.
I don’t believe a CPU bottleneck was present as I have an overclocked Ryzen 5 2600 running at 4.0GHz with a voltage of 1.35V, nor do I suspect memory constraints with 16GB of 3000MHz Crucial Ballistix RAM installed on a Samsung 970 Evo NVMe PCIe M.2 1TB SSD. As a medical student, my time is limited, so any assistance would be incredibly valuable.
