I wouldn't really call those mods. VoiceAttack is a completely standalone application and has nothing do to with DCS, and doesn't even know about it. Search for how to uninstall SRS and TacView. Can't remember if you have to do more that rename/delete the export.lua in the \Saved Games\DCS.xxx\Scripts\ folder and the relevant folders under \Saved Games\DCS.xxx\mods\tech My load times were improved by deleting other mods in the \Saved Games\DCS.xxx\aircraft and \Saved Games\DCS.xxx\tech folders.
Do you have any other real mods? The best way is actually using a mod manager, as that will uninstall mods by disabling them in the GUI, which makes troubleshooting very easy. Disable all, and then enable one by one the ones you need, to see if enabling one slows the startup time. One can also use a realtime log viewer like BareTail to watch the startup progress. (Pre latest update F-14 sounds took two minutes to load on my system , now it's all good ) I use Open Mod Manager, successor to OVGME, latest update was today. Cheers!
All the campaigns from Maple Flag are beeing redone to be compatible with the A-10C II. The first one is already done, and will show up under "Campaigns" for A-10C II, at least it does for me. More info can be found in the Maple Flag thread under "DLC Campaigns". Cheers!
