Menu performace drop while and after playing FC3 aircrafts

[foxtheancient]

I have a issue I guess only few encounter yet I saw I think two threads about it scattered around forums (with no final solution). I'd like to put it here because I found it to be FC3 related. Hopefully someone who can help will see it here.

 

Everything behave well before I start any mission with any FC3 aircraft or Su-25T. Just after start everything goes still well. However in some point (I didn't manage to find out when exactly) menu-related content goes terribly wrong and game restart is needed. Video may be better than thousand words so here you can see what it is about.

This is demostration for ME but affects all menu-related stuff both out-of-mission and in-mission. Flight itself (plane behaviour, cockpit instruments etc.) are suprisingly not affected so mission itself I can play with no issues. Unless I want to change some settings like key-binding for example. Interface is so slow it even does not recognize key press for new bind (I must select it from popup list).

 

As I said at the beginning it is only related to FC3 aircrafts (all of them - I really tried them all) and Su-25T. I have two other modules, Ka-50 and F-5, and I can play those all day without experiencing described problem. I tried a lot of stuff people usually recommend as driver updates, run as administrator stuff etc. with no effect at all. In my opinion as it is only related to part of the game content it is not performance or OS problem.

 

FC3 is basically unplayable for me because of this. I do welcome any idea.

I gave it another shot and tried to find out when problem occures. I did find it's cause. I really don't understand it though. Luckily fixing (or rather avoiding) it is quite simple.

 

First, I must apology to FC3 as it is not it's problem. However it appear only in FC3 aircrafts for a reason. As you know every FC3 aircraft (and Su-25T as well) has very similar keybind layout. Yes, problem does one particular key shortcut. It does not apper with Ka-50 and F-5 module because this shortcut is not used there (or just I'm not using it).

 

It is, for some stupid reason, shortcut Alt+L. Does not matter if right or left alt. Does not matter if pressed mid-flight or while in menu. Everytime pressed it does f***k the menu like in video above. Re-applying this shortcut does not return game to normal state. It has to be restarted.

 

I don't get it why Alt+L is somewhat problematic for DCS. Bug? Wonder if others encounter same behaviour. Solution is simple though. Never ever use Alt+L in DCS (some rebinding might be needed) and everything is fine.

Really strange problem. Maybe the key binding system has been corrupted somehow. It might be worth trying to repair your installation to see if that makes any difference.

That is super weird.

Might be worth trying to delete your options.lua and your saved games/dcs/config/input folders for the affected aircraft as well.

Make sure to back these up so you can re-import without losing your controls :)
