What are swap types and workarounds

[Anonymous]

Whenever you do a graphics card diagnostic you get swap types and workaround
recommendations. I have also heard talk of those in the newsgroups. What
do they mean and how does one implement 'swap type 4' or a "workaround 0'?

These are OpenGL settings telling Inventor which particular functions to use or not to use. Swaptype is the method by which the
display list is moved from the back buffer to the display buffer on your graphics card. Swaptype 4 is telling the card to use KTX
Buffer Flip extension which is slightly slower but more reliable than Swaptype 2 (simulate copy-swap using glCopyPixels extension).

Workarounds is just a cumulative collection various OpenGL extensions that can be disabled. 0x80000 is clear stencil buffer each
frame and 4000 is don't use bound textures.

The default settings can be changed only by editing the registry under
HKLM\Software\Autodesk\Inventor\RegistryVersionX\system\graphics\hardware library 2.0

The registry is a dangerous place, it is worthwhile exporting your registry to a file for safe keeping before doing any
modifications to the settings.

The safest thing to do is to apply the latest registry update from our
website (http://www.autodesk.com/us/inventor/graphic_cards/otherinfo.htm)

I don't know what card you have but the chances are that it will have a more
up to date optimisation settings than came with the shipping product
