How do I fix VRAM bandwidth spikes and steering lag in Farming Simulator 25?

I panicked when my Gigabyte RTX 5070 Ti AERO OC stuttered during autumn harvest, with VRAM hitting 95% and temps at 72-78°C per HWiNFO. I tried increasing the page file, but that dropped FPS to 45, making it worse. I then used GamePP Shader Compilation Queue Manager to clear 4.2GB of cache. 3DMark confirmed bandwidth stabilized at 92-96%, and HWiNFO showed temps dropping to 65-70°C. The tractor now moves smoothly.
