EDIT: Ok we've got a decent amount of feedback. Seems you cannot escape problems after all. It seems my flowmaps look fucked up on low settings, particles don't work an we have to remove refracting textures as they are causing a decent amount of framerate drops.
Thanks again people!
Hey dudes I need someone with CSGO to test my level sometime soon as my partner says he gets a huge drop in framerate when looking at the refracting textures but I do not. We also tested it on a powerful PC and it was fine so now I need someone with a so-so PC to test it for me.
All you need is CSGO and just add me on Steam : Habboi
Will be glad to test.
My girlfriend has C2D E6750 / HD 3800 / 4GB DDR2
She could probably test it too.
Strider I actually wouldn't mind you testing it. The framerate is fine on my PC but my friend has an even better PC and he gets some nasty drops. Let me know when you're free.
