This shows up on my Windows Desktop after a recent Steam update and reinstall of Skyrim. It also shows up in Steam under the Tools heading. AND, it offers an option to PLAY and shows that I've actually played it for 9 minutes back on 11/25/2004. I just did start it up again to see what it is and it's the Source Stress Test. However, under the Video settings, it won't change the screen to anything other than a 4:3 ratio....even though I can select 16:9 and 16:10. It just won't make the change. What gives? EDIT: Update-- OK, NM. I did get it to work...but, it seems I had to click the proper sequence of changes in order to get to my desired resolution. I actually was able to get it to run at 4K.
