Before we start, I play on a 2 year old laptop - so I already run my graphics on the lowest settings.
About 3 days ago, I could play fine, lag free, no freezing at all. Over the past few days I have been getting lag spikes and freezes that lasted about half a second. Now, at the time of posting this, I get 1 second freezes every 10 seconds and lag spikes frequently. I also tried installing the lower textures mod but that hasn't helped at all (and maybe even made it worse).
Is there anything I can do to fix this apart from formatting or getting a new computer?
