I found this (http://www.techspot.com/vb/topic68921.html) via Googling for a solution to speed up my Half-Life 2 installation. I decided to register because the people replying there seemed really polite and knowledgeable and I hope that you guys/girls can help me out with my awful HL2 performance. I put the settings well below what is "suggested" in the HL2 video options and I still have dire performance. Please help! Thank you so much in advance. I disabled all non-necessary services. Cleaned up my HD, defragged. Cleaned the registry, optimized it. Ran nTune automatic tuning for six hours last night. OS - WinXP Media Center (not sure it it matters) CPU - AMD Turion64 x2 Mobile TL-50 RAM - 1.46 GB GPU - nVidia Geforce Go 6150 256MB Thanks again! EDIT: I just noticed I named this thread the same as the previous. Sorry..
