Allot of object streamed at the same time will cause increased CPU and GPU useage, increasing the draw distance of objects will indeed cause lag for players with low end PC's. I advice you to not use to many objects in the same area if you know you're players have low end computers (which I guess is so since allot of samp players have crappy pc's)

Keep the draw distance as it is and don't use to many objects and you will be ok
