2021-04-11Fix: Check for a validly mapped OpenGL screen buffer during driver init. (#9007)Michael Lutz
2021-04-11Feature: allow a toggle to enable/disable vsyncPatric Stout
Vsync should be off by default, as for most players it will be better to play without vsync. Exception exist, mainly people who play in fullscreen mode.
2021-04-10Fix: Data races on cursor state in OpenGL backendsJonathan G Rennison
2021-04-09Fix #8930: [Win32] Don't handle printable keys on keydown if an edit box is ↵Michael Lutz
in focus. Handle printable input only when the matching WM_CHAR message is incoming. Without an edit box, do the handling in keydown as usual to support hotkeys.

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.
2021-03-08Codechange: don't set the window position when changing blitterMichael Lutz
There really is no need to make an extra call to the OS in these cases.
2021-03-08Remove: [Video] no longer draw in a threadPatric Stout
Drawing in a thread is a bit odd, and often leads to surprising issues. For example, OpenGL would only allow it if you move the full context to the thread. Which is not always easily done on all OSes. In general, the advise is to handle system events and drawing from the main thread, and do everything else in other threads. So, let's be more like other games. Additionally, putting the drawing routine in a thread was only done for a few targets. Upcoming commit will move the GameLoop in a thread, which will work for all targets.
2021-03-08Fix #8784: using alt+enter didn't update the fullscreen toggle visibly (#8820)Patric Stout
Basically, the window was not invalidated, so it was never redrawn. This made it look like it wasn't working, but it really was.
2021-03-01Fix #8775: [Win32] Don't create the main window when alt-tabbing back into ↵Michael Lutz
fullscreen.

fullscreen.
2021-02-28Add: settings to limit your fast-forward game speedPatric Stout
By default this setting is set to 2500% normal game speed.

Additionally, call it from the draw-tick.

2021-02-22Fix #6319: [Win32] don't use clipping; draw whole screen every frame (#8726)Patric Stout
When we clip the region that is only been redrawn, something weird happens on Windows. When pushing 60 frames per second on a 60Hz monitor, it appears that the clipped region is often shown of another frame, instead of the current. Examples of this are: - pause the game, move your mouse to the left, and at the right speed it totally disappears. - fast aircrafts seem to be in several places at once, weirdly lagging behind. - in title screen, moving your mouse gives you the idea it is jumping places, instead of smooth movements. In the end, if you do nothing, everything is correct, so it is eventually consistent. Just when we are firing many BitBlt in a clipped region, the in-between is not. What goes wrong exactly, I honestly do not know. On every frame that we push to the DC is a mouse painted, but visually it sometimes appears like it is not. Recording with external software shows it really is there. It is also not our eyes playing tricks on us, as the first example makes it really clear the mouse pointer really is not painted. And to be clear, with the mouse this is easiest reproduceable, as high-speed objects are influences by this most. But this happens for all movement that redraws small regions. Either way, not using clipped regions resolves the issue completely, and there appears to be little to no penalty (I failed to measure any impact of drawing the full screen). So better have a good game than fast code, I guess?
2021-02-20Codechange: Use C++-ism for zeroing.Michael Lutz
2021-02-20Codechange: deduplicate tick-handlers of all video driversPatric Stout
They were all identical, so better put this in a single place hoping it is less likely to break.
2021-02-20Change: [Win32] Remove force_full_redraw and display_hz settingsPatric Stout
These were special settings only for the win32-drivers, and introduced in the very first version we track. Time kinda had caught up with those variables, so it is time to say farewell. force_full_redraw was most likely a debug functionality "in case our dirty-rect fails". This should no longer be needed. display_hz was cute, as it had a max of 120. That is kinda out-dated information, but I also doubt anyone was really using this.
2021-02-20Codechange: [Win32] simplify when/where GdiFlush() is calledPatric Stout
2021-02-20Codechange: be consistent in what CheckPaletteAnim() does and when it is calledPatric Stout
Additionally, make sure this is a class method. Later commits will make use of this.
2021-02-20Codechange: be consistent in naming the paint function Paint()Patric Stout
Also move this function to be a class member. This to allow further deduplicating of code in a later commit.
2021-02-20Codechange: use (Un)LockVideoBuffer() to manage video bufferPatric Stout
2021-02-20Codechange: move all input-handling of video-drivers into InputLoopPatric Stout
2021-02-20Codechange: [Win32] make fast-forward check the same as with other driversPatric Stout
It was of all the drivers the only one doing this slightly different. When trying to unify more code, that was rather annoying.
2021-02-20Fix: [Win32] run InteractiveRandom() once every tick, not once every messagePatric Stout
Win32 was the only video driver doing this. It is just a bit too much random.
2021-02-20Fix: [Win32] now we are drawing on a tick, no longer use WM_PAINTPatric Stout
WM_PAINT hits when-ever Windows feels like, but always after we marked the screen as dirty. In result, it was lagging behind, giving a sub-60fps experience. With the new draw-tick there is no longer a need to be driven by WM_PAINT, so it is better anyway to drive the drawing ourself. As an added bonus this makes the win32 driver more like the others.
2021-02-19Fix: during switching of game-mode, drawing could show closed windows that ↵Patric Stout
shouldn't be closed yet The higher your refresh-rate, the more likely this is. Mostly you notice this when creating a new game or when abandoning a game. This is a bit of a hack to keep the old behaviour, as before this patch the game was already freezing your mouse while it was changing game-mode, and it does this too after this patch. Just now it freezes too a few frames earlier, to prevent not drawing windows people still expect to see.
