Argh! Scroll Lag is killing me!

Post by MonkeyBrain3 »

:roll:

Well,

I swear to God.... I really wished to play the game.

So I bought it during sale on Matrix Website.

Learning the game will be difficult.


But, For God Sake - scroll lag is killing my Wish to Even Play this game.

Please if there is a simple solution.

Win 11, i5, 16 GB....

I really want to sink some carriers ;)

Yes, there is an easy solution. This is dependent on the switches used in the properties of your short cut. There is lots of discussion on different switches available in the forum. You will be sinking carriers in no time. A better answer is provided by Google Gemini below. It has gotten surprisingly good at answering questions about WITPAE.

I currently use
-cpu2 -wd -deepColor -dd_sw -altFont -archive -skipVideo -pxf1920 -pyf1080 -altFont

Here is what Google Gemini recommends:

In the game War in the Pacific Admirals Edition by matrix games, the game is very laggy when I scroll. Which switches should I try to improve this?

Gemini said
The "scrolling lag" in War in the Pacific: Admiral's Edition (WitP:AE) is a classic issue on modern Windows systems (10/11) because the game’s older DirectDraw engine struggles with modern hardware acceleration.

To fix this, you need to use command-line switches applied to your game shortcut.

1. The "Big Three" Switches
If you only try one thing, try these. They bypass the hardware rendering that causes the stutter:

-dd_sw: This is the most critical switch. it forces DirectDraw Software emulation, moving the map rendering away from your GPU (which doesn't understand the game's old code) to your CPU.

-deepColor: Enables 32-bit color. Without this, Windows often tries to emulate 16-bit color, which creates massive interface lag.

-SingleCpuOrders: Restricts the game to a single CPU core during the orders phase. This prevents "stuttering" caused by the game's old engine trying to hop between modern processor cores.

2. How to Apply Them
You must apply these to a shortcut pointing directly to the game .exe, not the launcher (autorun.exe).

Navigate to your game folder and find War in the Pacific Admiral Edition.exe.

Right-click it and select Create Shortcut. Move this shortcut to your desktop.

Right-click the new shortcut and select Properties.

In the Target box, go to the very end of the text (after the quotation marks) and add a space, then paste your switches. It should look something like this:

"C:\Matrix Games\War in the Pacific Admiral's Edition\War in the Pacific Admiral Edition.exe" -dd_sw -deepColor -SingleCpuOrders -altFont

Click Apply and OK.

3. Recommended Performance String
For a smooth experience on a modern 1080p monitor, many players use this exact string of switches:

-dd_sw -deepColor -SingleCpuOrders -altFont -px1920 -py1080 -f -skipVideo

Switch What it does
-altFont Uses a much cleaner font that is easier to read at high resolutions.
-px#### -py#### Sets your resolution (replace #### with your monitor's width/height).
-f Forces Fullscreen mode (use -w for Windowed).
-skipVideo Skips the intro movies, which can sometimes crash the game on startup.
-cpu1 (Optional) Forces the game to use a specific core. Use this if -SingleCpuOrders isn't enough.
4. Important In-Game Settings
Even with switches, the in-game "Preferences" can cause perceived lag. Check these settings inside the game:

Map Scroll Delay: Set this to 0 or 1. If this is set high, the map will feel "heavy" or unresponsive when you push the mouse to the edge.

Show Hexside Details: Turning this OFF can significantly boost scrolling speed on weaker systems or very large maps.

Message Delay: Reducing this to 0 helps the game engine process interface clicks faster.

[!TIP]
Compatibility Mode: If switches don't solve it, right-click the .exe, go to Compatibility, and set it to Windows 7 or XP (Service Pack 3). Also, check "Run this program as an administrator."

I suggest using this utility on this thread to set up your switches. If you write them in, remember that the dash "-" at the top of the keyboard is different than the malus/minus "-" on the numeric keypad.

Then there's this and many, many other posts about the use of switches all done by humans. Off course the AI has just ripped off the work already done.

Thank YOU SO MUCH Gents!

I will use your technique and report back 🤠

The kingdom is ransacked, the jewels all taken back and the chopper descends
They′re hidden in the back, with a message on a half-baked tape with the spool going round
Saying I'm back here in this place and I could cry and there′s smoke you could click on.
