I'm with you, Rusty, I've tried everything suggested above, in fact, I tried every single one of them last February when I first got this laptop. Thanks for the ideas, though! I am fortunate to get a decent frame rate with the HD4600 integrated graphics, but it would be nice to see what this NVidia card can do! It works on all my Steam games as well as any other games, other game engines, etc. One thing of note that I found different this time around was that I was able to disable the integrated graphics and still get a desktop. I wasn't able to do that the last time I tried that, (had to connect an external montor) ~ yr ago. Perhaps all the driver updates, etc. have resolved that. Who knows? Who cares? I was able to launch Reloaded, but the editor only displayed black where (normally) the grass would be. I was able to place a start marker (which oddly showed with a lit area around it), but when I launched, nothing but a black screen. I felt as though I was almost there, perhaps a setting in the NVidia control panel, but I gave up there because I wouldn't have the faintest idea what to change!
With Integrated Graphics disabled:
Thanks, SC for the reply, I suspected you had one! The common thread, though, does seem to be laptops, but obviously not all; everyone that does have this issue has it on a laptop. Good luck to everyone! Please report back if you've found anything new!
