I bought a new computer and the curser jerks around and moves slowly like it's stuck in syrup. I replaced a an 8 year old computer which actually ran Chief better than the new one. The new specs are i7 with 8 gigs of memory and NVIDIA 4 gig graphics card. I checked the memory and updated all of the drivers. Anyone know why Chief ran better on the old one with less than half of these specs? Chief tech support was of little help.
