To outline my problem.....i'm getting 15-30 FPS at all times in Call of Duty 4. I need help with deciding whether I have: A) Faulty Hardware, B)Hardware that needs to be upgraded or B) Software issues. Call of Duty 4 Graphic settings(for those who are familiar) ---I have AA and AF OFF with Dynamic Lights, Model Detail, Water Detail, Texture Resolution, Normal Map resolution and specular map resolution ALL ON NORMAL. I have shadows, depth of field, glow, soften smoke, ragdoll and bullet impacts ON. I run the game on 1280X1024 Resolution. I have had 4-6 "iw3mp.exe"(which is a major executable involved with COD4) errors within the last month due to a monitor cable going bad and having to cold reboot with COD4 running. However this FPS issue has been there since installation of COD4. I have also noticed a 4-8 seconds freezing time every time I load COD4 at the main menu. Specs AMD Athlon 64 3500+ 2.2ghz(not overclocked) ATI Radeon X1650 Pro 512mb PCI-E 16x(not overclocked) 1 gig of generic RAM + 2 gigs of Patriot RAM (3 gigs total) MicroStar motherboard with Pheonix BIOS version 6.00PG 330 watt Allied Power Supply I run Desktop on 16-bit color, 60hz and 1280X1024 Res. I also run COD4 on 1280X1024 I've done the following things to clean my system up: Degragment, Disk Check, Full Disk Cleanup, cleaned all temp files..cookies...spyware, Antivirus, Windows Defender. DirectX Diagnostics says all hardware and software is working properly. My personal opinion and natural reaction is that my Processor isnt up-to-date with my RAM and/or video card. But i'm not sure. Also.......if my processor is the problem would overlocking it temporarily fix the issue until I buy a new processor?
