In your previous post
viewtopic.php?p=44066#p44066, it shows session names being assigned to the game.
It said
- Code:
"Session Name 'everquest game14192' accepted for process D:\games\EQ\eqgame.exe"
There should be a followup line, where this Session name is reassigned to IS1 (for the first slot anyway). If this doesn't happen (or it doesn't get assigned straight away), then Inner Space is effectively not recognising the starting up of the directx API (9 in this case). i.e. it has no control over the game process. This normally happens because something is preventing Inner Space from loading it's API interface into the game (most commonly various Antivirus packages or other software which is doing something similar), but there is nothing that appearing in your compatibility diagnostic that would indicate, or be a potential cause. This leaves a bit of a mystery.
Yes, your graphics card, and driver supports DirectX12. It also supports 7.0, 7.0a, 7.1, 8.0, 8.0a, 8.1, 8.1a, 8.1b, 8.2, 9.0, 9.0a, 9.0b, 9.0c, 10.0, 10.1, 11.0, 11.1, and 11.2.
In theory, it should also be compatible with versions 1, 2.0a, 3.0a,/b/c, 5.0, 5.2, 6.0, 6.1, and 6.1a too. Although you might be hard pressed to find anything requiring less than DX5 these days.
Part of the ISBoxer toolkit installation process makes sure that the appropriate DirectX libraries it needs are installed on your computer, and will attempt to install any missing components. You already said you tried this earlier and I did provide a link to the appropriate download for it.
DXDiags will only show you the latest and greatest library details, and not necessarily details of previous versions.
