Which of these features should I use: Guardband Clipping, Hidden Surface Removal or Z-Culling?
A. First of all, let me remind you that you should only choose one of these, or there can be crashes, visual defects and even performance loss. Guardband Clipping should be used in conjunction with a lower-class CPU, while HSR should be used with higher-end CPUs. Z-culling should only be used if HSR gives you too many visual problems (it’s slower than HSR, but gives less bugs).
