2021-03-25Change: Do not disallow persistent buffer mapping on AMD GPUs, as it is ↵Milek7
actually faster.
2021-03-21Fix f0f96e31: [OpenGL] Broken window resizing due to invalid buffer pitch on ↵Michael Lutz
texture creation.
2021-03-21Fix f0f96e31: [OpenGL] warning: comparison of integer expressions of ↵frosch
different signedness. (#8881)
2021-03-20Fix #8871: [OpenGL] Initialize all buffers after resize and clear back ↵Michael Lutz
buffer. (#8877)
2021-03-08Fix #8825: [OpenGL] Don't clear cursor cache from the game loop thread.Michael Lutz
2021-03-08Add: [Video] move GameLoop into its own threadPatric Stout
This allows drawing to happen while the GameLoop is doing an iteration too. Sadly, not much drawing currently can be done while the GameLoop is running, as for example PollEvent() or UpdateWindows() can influence the game-state. As such, they first need to acquire a lock on the game-state before they can be called. Currently, the main advantage is the time spend in Paint(), which for non-OpenGL drivers can be a few milliseconds. For OpenGL this is more like 0.05 milliseconds; in these instances this change doesn't add any benefits for now. This is an alternative to the former "draw-thread", which moved the drawing in a thread for some OSes. It has similar performance gain as this does, although this implementation allows for more finer control over what suffers when the GameLoop takes too long: drawing or the next GameLoop. For now they both suffer equally.
2021-02-28Fix #8763: [OpenGL] Cursor sprite origin can be negative.Michael Lutz
2021-02-27Fix: [OpenGL] Don't use OpenGL on MESA software renderers.Michael Lutz
Performance in this case is worse than not using OpenGL, so just let OTTD fall back to a different video driver.
