Windows 10 Stuttering/FPS lag FIX

Hey there. I run BF on Windows 10 and i had ingame fpslag/stuttering problems with my game for a while now. The game just did not run smooth. I used this workaround which worked for me for a while but stopped with another windows update i guess...: https://team-simple.org/forum/viewtopic.php?id=8562&p=1
Its quite tricky to install because u have to change the .dll in Windows/System... Not the best solution.

BF1942 is running on D3D8 which causes some problems with Windows 10 because its totally outdated maybe.
I did some research an found this:
https://github.com/crosire/d3d8to9

"This is a pseudo-driver module that intends to improve compatibility and stability in games using Direct3D 8 for rendering by converting all API calls and low-level shaders to equivalent Direct3D 9 ones. ..."

I tested this .dll for a while now and it works perfectly for me. The game runs really smooth now. You just have to download the file  (.dll only) and put it into your gamedir:
https://github.com/crosire/d3d8to9/releases
It's supposed to work like this for every old game based an D3D8.

Give it a try...
Cheers!

i´ve downloaded and placed ub the game folder´s root and the only thing that changes, is that i do not see how it charges the map. It goes from empty to full.

Re: Windows 10 Stuttering/FPS lag FIX

This especially might help people who are running the game at 144hz (or higher) Monitors. Others might not even notice problems. Depends on hardware, os, driver etc. also ...

My game settings btw. are:
renderer.lockfps 500 (VideoDefault.con)
game.setGameDisplayMode 1920 1080 32 144 (VideoCustom.con)

Re: Windows 10 Stuttering/FPS lag FIX

The most noticeable while ONLY using d3d8to9 are the text and the Icons in in-game menu and HUD were blurry at best, even at 1080p or higher resolutions. Plus, those who want also to run Rivatuner Statistics Server (RTSS) to monitor the CPU and GPU performance while gaming will not work OOTB, and any attempt to set the "Custom Direct3D support" to ON will lead to CTD after loading the EA/DICE videos.

I'd recommend to use d3d8to9 ALONGSIDE WITH DXVK to restore the sharpness and the functionality of those I mentioned above, but at the cost of janky fast-user switching, aka pressing Alt+Tab (as of the latest build).

Here's a video I posted for example:

Same here.

The only way to eliminate screen tearing is to use an adaptive sync monitor either with FreeSync (AMD) or GSync (Nvidia), and set the fps limit below the maximum refresh rate of the monitor for example 140fps for 144Hz.
