OK, I've installed the nGlide glide wrapper and done some quick tests. Here are my results so far...
Good:
+ easier to configure and use than dgVoodoo
+ no broken 2D cockpit
+ clouds don't jump (didn't look for myself but thanks Lorien)
+ I think my yaw appeared slightly better, I did say
slightly+ framerate does appear somewhat higher (chaingun rounds and rockets, most notably, seemed to travel faster)
+ slightly richer colors? (might just be my gamma setup)
Bad:
- not as many configuration options as dgVoodoo
- lines still present in 2D cockpit when you force higher screen resolution
- Hellfire and Maverick smoke seems to have a double smoke layer at immediate trail of missile
- I got several crashes during testing; one in-game freeze and a couple ghost screens upon mission exit
Summary:
What with the end mission and in-game freezes, plus smoke artifacts, I don't really think there is any overwhelming advantage over dgVoodoo. One or two things appear to be in nGlide's favor, but overall it is not as configurable and the main things like stability are still a big issue.
I decided to make a 'portable' version of the current latest version nGlide which you don't have to install. Just drag-and-drop files instead. I think I packed all the files needed, please see the readme I included for info. Note that you may have trouble downloading the ZIP file, my webhost is playing up a bit with not completing downloads before saying they have finished - leading to supposedly 'corrupt' ZIP files. If you have a download resumer, please use that to make sure the whole file is grabbed intact.
