I just reformatted my computer and installed a fresh copy of Windows 7 (64 bit). I tried to load NS2 afterwards and it only let me choose a maximum resolution of 1768x992 as opposed to 1920x1080. Also, it freezes the computer when I try to use the menumod. Any ideas as to what might be causing this?
I haven't done a lot to debug the issue, but not exactly sure what else to do (apart from reinstall windows again, which I probably will end up doing). I rolled back the NVIDIA graphics card drivers, tried it again, same issue. Then tried reinstalling (first time I did a "clean install", second time I didnt), and got the same issue again. I tried uninstalling NS2, and downloading it again (in case the problem was associated with migrating steamapps across), and still got the same issue.
I realize there's probably not a lot anybody can do, but if anyone can help that would be awesome. I haven't tried many other games to see if they run properly (don't really play any other games at the moment). I did test out Team Fortress 2 and it worked fine at 1920x1080 resolution.
