I'm having an issue much like one from earlier on this forum. I'm in the Industrial Zone playing as the exile (I had no issues playing as HK) with two party members and the lag is so bad that I can't move at all. Occasionally I can get the character to move but she jumps forward on the map and I can't control where she ends up. I've tried switching party members and going without them. I've tried disabling and enabling vsync, adding the Disable Vertex Buffer line into my ini, and I've got shadows and grass off. I've switched the graphics between high and low and it doesn't make a difference. I'm using the Steam version of the game and an Intel graphics card on Windows 7. Is there anything else I should be doing? Also, the only mods I'm using are the M4-78 mod and the most updated version of the TSLRCM.
