DXtory won't see GMod (or any source game)

Ever since the source filmmaker update came out yesterday DXtory just won’t see any source game i throw at it. It still sees all my other games so it cant be a problem with any background program.

You mean you can’t see any source games in your steam account?

I found a solution to this problem.

Right click Garry’s Mod in your Steam Library, go to Properties.

Click on Set Launch Options and put in this command: -nod3d9ex

This works for Dota 2 as well so it should also work for any Source game that DxTory cannot recognize.

Well, it doesn’t work for me and I don’t know why. Somehow I’ve systematically run out of screen-capturing software that actually works, even though my laptop’s powerful enough to run games just fine. Tried that little command and DxTory still doesn’t show anything in the process list, no matter what I’m doing in Garry’s Mod.
