Second Life runs very slowly, even with the graphics on low. The chat doesn't lag, but the actual game does. I use an Alienware M14x laptop. Processor: Intel Core i5-2430 CPU @ 2.40Hz (4 CPUs), Memory: 4096 MB RAM, DirectX Version: DirectX 11,Second Life FPS: 21.2 when away from users.

My avatar looks fine for me. But for other people I am missing parts to my avatar. No alpha layers, no tattoo layers, no nothing. This has only been happening ever since I cleared my Second Life's cache. My internet is slow, and Second Life has trouble reading my advanced graphics card(I use an Alienware MX14). Could that be apart of the problem? Is there any possible way to fix it? Please help, and thank you for your time!
