Hi, so it appears as though my ATI 5870 is underperforming a bit and the GPU keeps varying between 0% and 100% used (when checked via msi afterburner). This problem has only started happening for me over the course of the last few months. I'm not sure if it's supposed to do this, or if it's a driver issue... but it's been performing worse in games overall and just terribly in Battlefield 3 (20-40fps at any given time during the game on all low, except at the beginning, where it gets 60+ for the first 15 seconds of the game after loading up and me spawning. I'm not sure if this might be because the GPU is still being used entirely during that timeframe before it starts stuttering its usage or not.)
The FPS in the background is misleading in the pics (in between levels, not being read properly), but here they are:
Laptop: Asus G73JH
Processor: Intel Core i7 Q720 (1.6GHZ, 2.8GHZ turbo)
Video Card: ATI Mobility Radeon HD 5870
RAM: 6GB DDR3
Hard Drive: 500GB 7200RPM
The card's temperature when not being used stays around 73-75 degrees.
So, has anyone else encountered extremely low framerates from a 5870 mobility? Or does anyone know why it might be performing so poorly now?
