Hey. I recently updated, and many tools are lagging. For the first few brush strokes, it's okay, but any more of that and the newest version goes all wacky on me. All tools trail behind the cursor, causing a large delay from when I draw and when the strokes actually show up at that position. Said lines also render very choppy. I am running windows 10 pro with an i7 and GTX 970 FTW.
