I just reinstalled Source unpack on my new laptop, and even with lowest quality settings, i keep freezing and having low fps. I don't even have OBS running. I tried going in windowed mode, and it was even worse. Some help would be highly appreciated :D

There are a couple of things you can try:

• Set the priority for "hl2.exe" to High in task manager
• Disable autosaves by typing "sv_autosave 0" in console

Hope these help :)
