I use Firestorm viewer. My computer runs windows 10 and has a NVIDIA processor. SL used to run very slowly and always had a lot of lag. So much lag that it was hard to steer my avatar straight. Suddenly It began to work normally, without lag every single second. This lasted less than a month. One day, my computer lost power while I was logged in, and once power was restored, SL temporarily reverted back to being very laggy, before quickly working well again. Now my computer has now lost power again, and now that power is restored, SL seems to be permanently laggy again. SOMETHING must me making SL sometimes work well and sometimes not, but I have no Idea what. Anyone have any ideas?

My Computer has a Nvidia Geforce graphics card. I use the Firestorm Viewer. SL was running fine until firestorn informed me that it was no longer using my nice Nvidia graphics card, and that it is using my internal Intel Graphics card instead. Now there is too much lag for my avatar to even walk sometimes. How do I tell firestorm to actually use the better graphics card?
