pulsar effect role play

We need more information than that. What map are you joining? What kind of effects, does this “Pulsar Effect Role play use?” Does Garry’s Mod even support 64-bit Windows 7?

The map is rp_evocity_v2d, and The effects are like wild fires and npcs different jobs, Other games I play like l4d, css, tf2. Runs fine but sometime they freeze.

Yes it does. I’m using windows 7 64 bit. Works fine.

In fact, all games work fine and I’ve even gotten a 10 - 30 FPS increase in all games.
