the release of the latest 3dfx BETA driver for the
Voodoo 4/5 PCI/AGP everyone has been going on about
HSR & performance increases. So what exactly is
HSR & how can I use it ? Read on.
= Hidden Surface Removal. The
basic concept behind HSR is fairly self explanatory
from the name – What can’t be seen shouldn’t be
rendered. This can of course greatly improve
performance as the video card no longer renders
objects which aren’t visible (Every video card
around still renders a lot more than what is
HSR is not performed by the graphics card, rather by
the CPU (Or T&L unit potentially if available,
although this is unavailable on the Voodoo 4/5). As a
result performance gains from HSR are largely CPU
dependant. Currently HSR exists in BETA form, so many
of the graphical errors or other workarounds mentioned
here will inevitably become redundant as 3dfx fixes &
optimizes the implementation.
on Start, Run, type in regedit
& hit Enter. Go to the following registry
Surface Removal], where x represents the
folder with the Glide sub-folder.
click on the Disabled value & select Modify,
change the value from 2 to 0 & hit Ok.
This will enable the display of the Hidden Surface
Removal setting in 3dfx Advanced Features. However to
ensure the setting remains there you must make 1 more
change. Right click on the Hidden Surface Removal
folder & select Rename. Add a blank
space after Removal. You can now exit regedit
& adding this blank space (Thanks Jam). This will
ensure that the setting is not removed from 3dfx
Advanced Features after a reboot.
