In this modified version of Dosbox called SVN r4019.3 Pixel-perfect/Savestates/VSYNC an option for internal software vsync was added instead of handling the one of the windows graphics card by hardware, they made it internal managed by software with an option called borderless=true: The solution to this should be to implement the same opengl output from Dosbox 0.74 in Dosbox-X, because they don't seem to be the same opengl and it doesn't handle FPS as well as the original Dosbox 0.74 does.Īnother solution could be to add a built-in Dosbox vsync and disable Windows vsync in Dosbox and it could solve it like this, in this way Dosbox could handle its own vsync by software without the need to do it by hardware or by windows and it could fix the lag problems in games or it would be much more stable to do it by software vsync. Jazz Jackrrabit 1 in Dosbox 0.74 with svga_s3, opengl and my Nvidia graphics card with vsync activated in Windows, it always handles it at a fixed 60FPS automatically and without any lag when you move from one side to the other of the game level, but in Dosbox -X in the same configuration does not handle fixed or stable 60FPS and having vsync activated from windows, doing it in Dosbox-X gives some small lags, but I have discovered that it is due to the handling of the opengl output, Dosbox 0.74 can do it well no lags having vsync but in Dosbox-X with opengl and vsync in Windows it gives small lags that in Dosbox 0.74 do not occur, due to the programming of the opengl output in Dosbox-X, Dosbox-X seems not to be exactly the same opengl as the of the original Dosbox 0.74 and it should be fixed, when used with graphics cards with vsync, there is no fixed and stable vsync in Dosbox-X and it should be fixed and adopt the same opengl of Dosbox 0.74 in Dosbox-X because the FPS is fixed and stable. With this configuration I can get all the power of svga and opengl in games but I also have VSYNC activated on my Nvidia graphics card from Windows so that both Dosbox 0.74 and X get vsync, but I have noticed that Jazz Jackrabbit in the original Dosbox 0.74 with the Same configuration, when I move the character from one side of the game to the other, Dosbox 0.74 does not give any lag and the FPS remains fixed at 60FPS or so it seems, however I have tested it in Dosbox-X with the same configuration and Jazz Jackrabbit It gives some small lag in the FPS, I have made several configurations choosing other scalers and other different machines, the same problem and in the end the only one that seems to give the problem is the opengl output.

(I have noticed that fullresolution in 1280x800 is corrected to a real full screen without having black bands above and below in Jazz Jackrabbit) My configuration on both the original Dosbox 0.74 and Dosbox-X is all from the factory except these options when I play Jazz Jackrabbit among others:

I have noticed that the OpenGL of Dosbox-X is not as accurate in the FPS of some games as in the original Dosbox 0.74, I have noticed it especially in the game Jazz Jackrabbit 1 both in Dosbox 0.74 and Dosbox-X and Dosbox 0.74 keeps all the I spent the 60FPS of the game without any slight lag when moving from one side of the level to the other, which with Dosbox-X I have noticed that it does have small lag jerks from time to time.
