Thanks but i sorted the issue i downloaded AVG Tune Up, and now i can play tekkit with sphax on around 45fps <object class="emojione" data="https://resources.enjin.com/1489581540/themes/core/images/emojione/svg/1f642.svg?0" type="image/svg+xml" standby=":)">:)</object>

Does anyone know what i can do to make tekkit run faster? i can only get like a max of 25fps. I have a Laptop which is a Inspiron 1545, is there anyway to improve performance?
