Same problem here, AMD Athalon II X4 640 Processor 3Ghz, MSI GTX 460 Hawk 1GB, 4GB Ram. Playing Wasteland in Chernarus no matter how high or how low I set settings and resolution FPS at highest goes to around 22fps, averages to 15fps and drops to 8fps after server has been running for a 2-3 hours. On this map GPU usage is anywhere between 20-8%. Started trying Wasteland Takistan and I'm actually seeing almost 50% GPU usage and sometimes 40-45FPS, still drops to around 25% at times but FPS still at a playable 25FPS...but in here almost all high settings. 200 pages almost, 3 1/2 years of posts, and this hasn't been fixed?
