The top end rune with +1 skills. Is it saying it’s a normal +1 skills instead of increasing skills for pets? I used to think it would not increase your pet levels, but it should for ALL skills including pets right?
Just like any other +1 all skills?
I don’t complain if the game has been running a whole day and it goes black. Once in awhile. I did get the Act 1 passage crash in Hell, went to level two which I usually don’t do, lost experience permanently after dying to the world boss. That’s my only crash with this character that I can recall, but it’s been 6 months in the making.
Been running on the DSR setting below 3x right now as a balance for the UI and actual improvement vs. performance. I installed this cursor mod, the remastered version that’s not nearest neighbor and the cursor is now BEAUTIFUL:
8x AA seems to clear things up ALOT! I do sharpen to max, which is technically 200%. That’s because I’m not running normal 4x DSR like usual, I’m doing 100% smoothness and setting the desktop resolution to the EMULATED resolution, and then in turn the game resolution to match. It’s a much stronger effect and has more blur. Between the blur and the sharpen it’s basically a remaster of the game. I posted that here as this mod has some super old assets from TQ in act 2 that’s not good. 
The mod installs in the My Documents (look at instructions) so is independent from RoT and SUPER easy to install!
I really enjoy the smoothed out textures. I can slow down a bit on a gtx1080 but with only 2x supersampling and it’s smooth most of the time. I don’t even have my card OC’d right now (forgot after my machine was hacked).
Almost through hell, still feeling very balanced, tough to keep up the damage without endgame gear to keep it going fast, but otherwise it’s not been that hard in this minion based build. I’ll try world bosses and ubers soon if I don’t get bored. 
I may choose these settings with base GD later but it’s not nearly as needed as this mod, it really boosts the visuals a great deal. I don’t usually use AA, but it seems to make it look far better with DSR/sharpen than usual. I have it at 8x. I never tried it like this before with desktop DSR AND AA, it’s a double load and made my old 1GB card go to a slideshow if I accidentally turned it on. 
I was just tired of the bad old textures in both GD and RoT. The best test for framerate is act 3 with all those gidbin warriors around. If it can handle the 30 enemies or so running at you, you should be good for the rest of the game. 
Summary:
2.25? DSR with desktop resolution set to it.
100% smoothness with DSR
200% sharpen (EDIT, just added, forgot this one) aka., slidebar all the way to the right
Game set to desktop virtual resolution.
AA settings at 8x (if your system can handle it)
2x SS (supersampling) as higher settings will destroy your framerate
I got this performance and fantastic visual quality from the LATEST Nvidia driver where sharpening and SS were all reworked and running much better. Thanks Nvidia.
The result should be you no longer see bad artifacting or super blurry textures. Depending, text may be blurred a bit. Settings for a 1440p monitor only, if you have a 4k monitor just run at native resolution of the monitor and try some of the other settings! Try 1.5x DSR to get a light blur and see if that helps, suicide on a 4k to go higher, but it’s the only way to get the smoothness setting turned on, which will help the textures when you sharpen them up (don’t sharpen it as much on a 4k display as there’s less blur).
If your UI is too small you can adjust it manually in the text settings file for the game itself, but not for the cursor which requires the mod (I looked that up on Google search).
I may try DSR 4x but I doubt it’s necessary, the more you smooth it out the more texture detail is lost and your framerate is affected.
As a bonus I use a similar technique with VLC player on old TV shows (with desktop DSR, 2.25x or 4x for really grainy shows). It has a guassian blur (called spacial blur in the player under advanced) and a sharpen you can run simultaneously, for best results uncheck and recheck the sharpen filter before applying effects, it looks best if you set it to sharpen the picture before you blur it, as it gets rid of any artifacts. Can work with low quality 720p to 480p or less, more will cause you to lose frames. gtx1050 or higher recommended. Gaussian blur shouldn’t be much past the first bar on the slider or the sharpen will never be enough, the sharpen itself is trial and error depending on the input video, for anime/cartoons go much softer.
