"Launch KSP" causes performance issues

Summary
Launching KSP v0.90 via CKAN's "Launch KSP" function results in ridiculous amounts of RAM usage even though no mods are actually installed. Launching via the usual KSP.exe does not do this.

Versions
KSP version 0.90.705 x86 ~ CKAN version 1.3.6 ~ System info

Details
Launching KSP via CKAN (no mods installed) results in memory limit being reached before it even finishes loading (image). Launching KSP via the stock launcher .exe (no mods installed) is successful and uses just over 2gb of RAM (image)

How to reproduce

1. Install KSP v0.90.705
2. Install CKAN v1.3.6
3. Do not install any mods
4. Run KSP via stock launcher app or .exe
5. Note RAM usage
6. Close KSP
7. Launch CKAN
8. Click "Launch KSP"
9. Observe RAM usage throughout loading process. It should jump up to almost 3gb before any parts are loaded.

This may be my fault, I've put the -force-opengl flag by default, could you remove it from Settings -> KSP Command Line and check if you have the same issue?

I cannot reproduce the issue on my system: however, I normally use opengl, so this might be the reason.
I will report your solution to the OP, it makes a lot of sense :)

I'm the original submitter. Removing the -force-opengl flag worked perfectly. Thanks!

Great to know! I propose we leave this issue open until the option is removed from the default in the next update.
