Anyway to increase performance? I already turned down shadows/textures, but there seems to be no difference.

AxelxGabriel,
I can't be certain, but I think you might be helped by adding -force-d3d9 into the start command; from this link: https://www.gog.com/forum/wasteland_series/screen_tearing_aka_vsync.

Where do I put -force-d3d9 exactly?

It will be part of the command line. So if you're starting the game by clicking a link in windows, right click the link, select properties, and add -force-d3d9 immediately after "WL2.exe". It should read something like this, without the quotes: "WL2.exe -force-d3d9" -- but I've not been on a windows system to see exactly how it would lay out.

When I did that and clicked it to start, it asks me what program to open the file with.

In the "start command" as Claimant said. That is the line that launches the application. On my os and for my implementation of W2 it looks like this:

"C:\GAMES\GOG Games\Wasteland 2\WL2.exe"

If you add the parameter -force-d3d9 to the end of the program launch, then the program will accept them as parameters and modify its behavior. For my pc I go to properties on the shortcut to W2 and find this launch command under the title: "Target".

-edit- Well this is a fast topic! As for "When I did that, it's asking me what program to open the file with." it sounds like you messed the command line up somehow, so it no longer knows what program to execute. Did you accidently delete the prior contents of that field?

-edit#2- To save time, why don't you copy and paste to this thread what your current (failing) command line looks like?

\Desktop\GOG Games\Wasteland 2\WL2.exe-force-d3d9

Make sure there's a space. It should be the path (C:\GAMES\...) then executable (WL2.exe) then a space and then -force-d3d9.

Oh yea, as C said you need a space after exe and before any parameters.

PS: Did you really install it to your desktop?

I'd guess, rather, that (s)he's updating the desktop shortcut. If that's how (s)he always launches it, that's fine. Modifying the target file might be better, just in case, but shouldn't be necessary.

No I added the space, it's still asking me for what program to open the file in, both shortcut and original .exe

This might be my fault. Try making it this: "\Desktop\GOG Games\Wasteland 2\WL2.exe" -force-d3d9
In order to have the space for Wasteland 2 directory without breaking the commadn, there might need to be quotes that I told you to remove. My apologies.

Can you open file explorer and do a search for wl2.exe? Whatever you are pointing to in your command line is not where the executable is. At a guess your file can be found in:

c:\GOG Games\Wasteland 2\

If so, you command line should look like:

c:\gog games\wasteland 2\wl2.exe -force-d3d9

-edit- ah? The quotes are mandatory?

I'm not sure if they are. Back when win95 came out they were, and I seem to remember more modern win-machines adding them on tab-completions in cmd.exe. Unfortunately, I only use windows at work... and do not keep up with all the changes that might apply. I suspect they are, however, as otherwise the space between GOG and Games would indicate an end of command, and the rest would be interpretted as an option.

Finally! It works! I just had to put it outside the quotes. And just in time for my first encounter too :)
