Doesn't forcing v-sync through dgVoodoo help?

No, as this caps the framerate to screen refresh (60 Hz in my case) and makes the games unplayable slow.
Btw, the mentioned games don't run with a constant framerate when wrapped. It varies between 0 (static screen) and >1000 (moving mouse cursor).

A way to limit FPS to an arbritrary value with dgVoodoo2 would be ideal for this type of problem, I think.

VSync helps for 3D games, but some games (whether they are 3D or not) are quite stubborn.

And vsync with a 144hz monitor is useless if game don't like 144 fps.

I bump up this thread to ask if the latest WIP (WIP65) solves the problem.
The symptoms you described and the insane FPS make me guess those DDraw games draw a lot of screen elements part by part directly to the primary surface.
Doing so is always causes problems, like the flashing game cursor in Baldurs Gate2 (DDraw). That game is locked to 30 fps but runs on 90 because 2 extra swapchain flip are taking place for each frame because of drawing the mouse cursor.

In WIP65 I introduced a new option (Batched update for primary surface) that is enabled by default, and it should throttle the fps to the screen refresh rate.

I can confirm that with "PrimarySurfaceBatchUpdate=true", the games now work fine with reasonable framerates. But it only works with normal version 62, not with WIP65.

Wing Commander II Kilrathi Saga edition suffers from this badly
All cutscenes and dialogues Besides the Voiced ones runs a incredibly higher framerate speeds

stinger was trying to patch this, but he's tied with his job for god knows when blizzard decides to release War3Reforged.

Thanks for the report! WIP65 doesn't matter by now, I remember I did some changes after that, for 2.62.

Even with PrimarySurfaceBatchedUpdate enabled? Can't that be just solved by forced vsync?

Even with forced Vsync and set it to true, the game's animations speeds up insanely in dialogues, intro and cutscenes, unless its voiced.
