I recently upgraded my GPU from an AMD Radeon RX 6600 to a Sparkle Intel Arc B580 Titan. While I see significant performance gains in some titles, I am experiencing severe instability and inconsistent GPU utilization in others.
Performance Observations
Assassins Creed Valhalla (Only-Success): This game runs perfectly. On my old RX 6600, I used to get 70-80 FPS with optimized settings. With the B580, I have maxed out every setting and comfortably achieve 90+ FPS.
Crimson Desert (Unplayable): The game suffers from extreme stuttering. While the FPS occasionally reaches high peaks, it frequently drops to unplayable levels.
Marvel’s Spider-Man (Unstable): Initially, the game performed well, maintaining 70-80 FPS on maximum settings with Ray Tracing enabled. However, the performance eventually degraded, resulting in heavy stuttering and unplayable frame rates.
GPU Utilization & Driver Overhead
The most concerning issue is the inconsistent GPU utilization. On my previous RX 6600, GPU usage was consistently at 99% during gaming. On the Intel Arc B580, the usage is highly unstable; it frequently drops to 60% or lower and fluctuates wildly. It feels as though there is significant driver overhead or a bottleneck preventing the card from maintaining a steady load.
System Specifications
CPU: AMD Ryzen 5 5600
GPU: Sparkle Intel Arc B580 Titan OC
Motherboard: MSI B450M-A Pro Max (PCI-E 3.0(I think its not the problem))
RAM: 2x8GB=16GB RAM DDR4 3200MHz
Storage: 1TB Kingston NV2 NVMe SSD
Power Supply (PSU): DeepCool PK550D 550W
Monitor: LG UltraGear 24" (1920x1080p, 144Hz, 99% sRGB)
Settings: Resizable BAR is Enabled.
Bios: Bios is up to date.
Troubleshooting Steps Taken
Driver Cleanup: I used DDU (Display Driver Uninstaller) to completely remove the previous AMD drivers before installing the new card.
Intel Driver Installation: During the Intel software setup, I specifically selected the "Clean Install" option to ensure no remnants of old configurations remained.
Request for Assistance
I am looking for advice on how to stabilize this performance. Since Re-Size BAR is already active, what specific optimizations or driver configurations are required to ensure consistent GPU utilization and eliminate the stuttering in these titles? Any guidance would be greatly appreciated.
