I've run into this issue for a while now and I'm really needing to work past it. My program is really laggy on modern computers. I've tried it on a handful of laptops with SSD's, some with GPUs and some without. On each, the program stutters like crazy. Smooth easing results in instant movement, smooth menus are laggy, etc. Even keypresses are laggy.
On older machines or machines with HDD's, the program runs fine.
My program has light usage requirements and doesn't use much in the way of graphics. I have it set to 'Standard' display mode since some older extensions I use require that.
Any ideas as to what's going on? I really need to figure my way around this as I have an educational app in use in some schools and they've reported the issue (I was already aware of it so I know it's not specific to their machines). I am not 100% sure the SSD or Win10 is the issue but I'm seeing this on a lot of new machines.
