Start GBPVR with command line switches?

[4zm4r3d02]

I want to start GBPVR with a window size of 640x480. I made a batch file with the following lines:

@echo off
"C:\Program Files\devnz\gbpvr\GBPVR.exe -pos:0,0,640,480"

When I run the batch file, a command window flashes briefly, then nothing happens. However, if I then change the batch file commands to the following, GBPVR will start with a window size of 640x480, but the command window doesn't close:

@echo off
"C:\Program Files\devnz\gbpvr\GBPVR.exe"

Can someone please tell me how to create a batch file that will start GBPVR with the desired window size, without leaving the command window open?

ps I have window mode enabled in GBPVR config

Maybe you could do something like:

@echo off
start "C:\Program Files\devnz\gbpvr\GBPVR.exe" -pos:0,0,640,480
