Yep, Witchaven's laggy controls were a real problem.

I have this game. Tons of issues due to clockspeed. Check https://ettingrinder.youfailit.net/wh-egwhaven.html for tips and the EGwhaven version. It's better but some clockspeed issues remain (turning around in simple levels at warp speed).

Very cool resource, thank you! Will read through it and try that unofficial patch. Interesting point on clockspeed. It is not a game that I would have thought would have been impacted. Will have to pull out my pentium machine and try it on it as well. That is after all more in line with the system I used as a kid to play it on... My P2 400 is an unlocked version, will also have to try reducing the multiplier and slow the system down...

Wow, just using the EGwhaven patches has made a significant improvement to Witchhaven 1! Getting an error launching 2 that I am researching...

So using EGWH2 when set to 640x480 results in an error DPMI_mapPhysicalToLinear() failed!

But if I run the normal WH2.exe when set to 640x480, the game runs...

Interestingly it runs fine at 640x480 when ran within Windows and it works in my DOSBox install on my modern PC...

You could try this : http://www.sierrahelp.com/Utilities/DisplayUt … ties/NOLFB.html

My guess is intentionally disabling use of the VESA LFB under Windows, but trying to use it under DOS and somehow failing with your video card .

Maybe there is an issue with your video card's VESA BIOS .

On a whim, I tried an older version of DOS4GW and overwrote the one supplied with EGwhaven and I can run in 640x480 mode now...

Version 1.97 (260KB) is what is provided with EGwhaven, I used version 1.95 (249KB)

Cool .

You could also try DOS32A , it is an open-source drop-in replacement for DOS4GW.EXE . You can rename it to DOS4GW.EXE , or if DOS4GW.EXE is embedded in the main executable, start the game with dos32a.exe game.exe (where game.exe is the game's executable ).

It is embedded in the original executable, but in the EGwhaven "patch" there is a standalone version supplied. What is interesting is the newer version works with Witchaven 1...

I saw the NOLFB patch, but saw it was for XP and newer systems... That is what gave me the idea to replace the version of DOS4GW version...

Great that it works! For me it makes a difference, but I notice it's still sensitive in certain area's. Where it first was slow and felt like having glue under my shoes with running and jumping, it now runs ok, but level complexity can cause some issues. And I think the artwork for Witchaven 2 is higher resolution to accommodate SVGA, might explain why Witchaven 1 runs a bit better.

so far gameplay has been great with EGwhaven... I have found a few very localized places where it slows down. It happens it seems at defined areas and is reproducible. However I am not able to reproduce it in DOSbox...

changing the speed of the CPU or disabling cache doesn't have any impact.
