It's not smooth vs D2DX

[weili0677]

when I use the cnc-ddraw in Diablo2,render is OpenGL,and the FPS is 60，but seem not smooth.

I use the D2DX in Diablo2,FPS also is 60,and play very smooth.（but D2DX have some bug will let game crash）

so can you fix it?

show you config. this is my config:

; cnc-ddraw - https://github.com/CnCNet/cnc-ddraw - https://cncnet.org

[ddraw] ; ### Optional settings ### ; Use the following settings to adjust the look and feel to your liking

; Stretch to custom resolution, 0 = defaults to the size game requests width=1738 height=976

; Override the width/height settings shown above and always stretch to fullscreen ; Note: Can be combined with 'windowed=true' to get windowed-fullscreen aka borderless mode fullscreen=false

; Run in windowed mode rather than going fullscreen windowed=true

; Maintain aspect ratio maintas=true

; Windowboxing / Integer Scaling boxing=false

; Real rendering rate, -1 = screen rate, 0 = unlimited, n = cap ; Note: Does not have an impact on the game speed, to limit your game speed use 'maxgameticks=' maxfps=0

; Vertical synchronization, enable if you get tearing - (Requires 'renderer=auto/opengl/direct3d9') ; Note: vsync=true can fix tearing but it will cause input lag vsync=true

; Automatic mouse sensitivity scaling ; Note: Only works if stretching is enabled. Sensitivity will be adjusted according to the size of the window adjmouse=false

; Preliminary libretro shader support - (Requires 'renderer=opengl') https://github.com/libretro/glsl-shaders ; 2x scaling example: https://imgur.com/a/kxsM1oY - 4x scaling example: https://imgur.com/a/wjrhpFV shader=Shaders\cubic.glsl

; Window position, -32000 = center to screen posX=98 posY=41

; Renderer, possible values: auto, opengl, gdi, direct3d9 (auto = try direct3d9/opengl, fallback = gdi) renderer=direct3d9

; Developer mode (don't lock the cursor) devmode=true

; Show window borders in windowed mode border=true

; Save window position/size/state on game exit and restore it automatically on next game start ; Possible values: 0 = disabled, 1 = save to global 'ddraw' section, 2 = save to game specific section savesettings=1

; Should the window be resizable by the user in windowed mode? resizable=true

; Enable linear (D3DTEXF_LINEAR) upscaling filter for the direct3d9 renderer d3d9linear=true

; Enable upscale hack for high resolution patches (Supports C&C1, Red Alert 1 and KKND Xtreme) vhack=false

; cnc-ddraw config program language, possible values: auto, english, chinese, german, spanish, russian, hungarian, french configlang=auto

; Where should screenshots be saved screenshotdir=.\Screenshots\

; ### Compatibility settings ### ; Use the following settings in case there are any issues with the game

; Hide WM_ACTIVATEAPP and WM_NCACTIVATE messages to prevent problems on alt+tab noactivateapp=false

; Max game ticks per second, possible values: -1 = disabled, -2 = refresh rate, 0 = emulate 60hz vblank, 1-1000 = custom game speed ; Note: Can be used to slow down a too fast running game, fix flickering or too fast animations ; Note: Usually one of the following values will work: 60 / 30 / 25 / 20 / 15 (lower value = slower game speed) maxgameticks=-1

; Windows API Hooking, Possible values: 0 = disabled, 1 = IAT Hooking, 2 = Microsoft Detours, 3 = IAT+Detours Hooking (All Modules), 4 = IAT Hooking (All Modules) ; Note: Change this value if windowed mode or upscaling isn't working properly ; Note: 'hook=2' will usually work for problematic games, but 'hook=2' should be combined with renderer=gdi hook=4

; Force minimum FPS, possible values: 0 = disabled, -1 = use 'maxfps=' value, -2 = same as -1 but force full redraw, 1-1000 = custom FPS ; Note: Set this to a low value such as 5 or 10 if some parts of the game are not being displayed (e.g. menus or loading screens) minfps=-1

; Disable fullscreen-exclusive mode for the direct3d9/opengl renderers ; Note: Can be used in case some GUI elements like buttons/textboxes/videos/etc.. are invisible nonexclusive=false

; Fixes issues where the pitch of a surface is not a multiple of 4 ; Note: Enable this if some parts of the screen are being displayed diagonally fixpitch=false

; Force CPU0 affinity, avoids crashes/freezing, might have a performance impact singlecpu=true

; Available resolutions, possible values: 0 = Small list, 1 = Very small list, 2 = Full list ; Note: Set this to 2 if your chosen resolution is not working, set to 1 if the game is crashing resolutions=0

; Child window handling, possible values: 0 = Disabled, 1 = Display top left, 2 = Display top left + repaint, 3 = Hide ; Note: Disables upscaling if a child window was detected fixchilds=2

; Set the precision for Direct3D9 floating-point calculations to the precision used by the calling thread ; Note: Enable this if there are desyncs in online games fpupreserve=false

; ### Hotkeys ### ; Use the following settings to configure your hotkeys, 0x00 = disabled ; Virtual-Key Codes: https://docs.microsoft.com/en-us/windows/win32/inputdev/virtual-key-codes

; Switch between windowed and fullscreen mode = [Alt] + ??? keytogglefullscreen=0x0D

; Maximize window without frame = [Alt] + ??? keytogglemaximize=0x22

; Unlock cursor 1 = [Ctrl] + ??? keyunlockcursor1=0x09

; Unlock cursor 2 = [Right Alt] + ??? keyunlockcursor2=0xA3

why maxgameticks=-1 and singlecpu=true

[weili0677]

why maxgameticks=-1 and singlecpu=true because vsync=true so I set maxgameticks=-1 and singlecpu=true because I find out cpu higher then =false

[FunkyFr3sh]

You have vsync and windowed mode enabled both at the same time, this is not a good idea (it will add a lot of input lag).

On windows 11, 10, 8 Do never enable vsync and windowed mode at the same time.

On windows 7, vista If aero is enabled: Do never enable vsync and windowed mode at the same time.

If aero is disabled: You can enable both at the same time if you want

On windows xp You can enable both at the same time if you want
