IF YOU HAVE A SOLUTION PLEASE TELL ME IN THIS FORUM:
Yes that worked it made it less laggy but the next problem is I made a light and light switches using a video by Omogonix* and when I turn it on it lags the game when its on and I think its because the size of the OmniLight3D but I tried resizing it and that worked a little bit but it still lags when it is on. Is there any way to fix the lag completely?
