Here is some feedback

- The default gamma is a bit too bright compared to the software version
- The menu animations are choppy compared to the software version
- There is increased input delay at 800x600 and significant input delay at 1024x768
- The difficulty levels are named differently than the original US version (Maybe a regional difference?)
- The horizontal resolution still seems to be limited to 320px for geometry and texture co-ordinates, I assume that is because of the way column rendering is converted to 3D and it only has fixed 320 columns unlike duke3d which has 800 columns in 800x600 mode. I wonder if there is a way to get the game to calculate 640 or higher columns internally.
- The end of level screen doesn't appear

For completeness I think you should also patch the shareware version (the hunt begins) since it has the unique first chapter

Update: 30/10/2026, V1.00a

1Many bugs fixes related to last reports

I will do the shareware version on next update.

Update feedback

- Default gamma is fixed
- Menu animations are fixed
- Internal column resolution now matches output resolution, output is significantly cleaner
- Original US difficulty levels restored

- The menu is a mix of filtered and unfiltered segments, e.g. the menu title is unfiltered, the menu itself is filtered. The whole menu changes from filtered to unfiltered during fades. Maybe the best option is to disable filtering in the menu objects entirely for consistency. Not a functional issue, just aesthetic consistency.
- Input delay is improved, 800x600 is now playable with only a small amount of delay. 1024x768 still has too much delay to be enjoyable.
- End of level screen still missing/not visible
- The game's original timing is for VGA 70hz, the 3DFX display mode is 60hz. Has the game's timing been adjusted to match the new frequency? Small stutters even at 640x480 indicate the internal and display rates are not matched (35fps -> 60hz). Not critical but does make it feel less smooth than the software version.

1Now support both Full Version and Shareware versions !
2Many bugs fixes related to last reports

Update feedback

- Input delay greatly improved, now playable at 1024x768
- Menu filtering/appearance fixed
- Refresh rate stutter fixed
- End of level screen fixed

- The rise of the triad intro sequence looks pretty cool with bilinear filtering, but it has a glitch where the right side of the screen is corrupted once the logo zooms out
- Needs some performance optimisation, framerate in 3dfx mode is lower than software in some areas. I will attach a save game with an example after testing some other updates.
- There is a single line of garbage pixels above the status bar at the bottom of the screen when in game

Edit: attached save game, fps reduces below 35 when looking at the barrels and windows. I suspect there is a lot of overdraw and it is hitting a limit on the GPU. Given the simplicity of the graphics and the power available it shouldn't be dropping below 35fps one would think.

It's also worth mentioning that the stutter has been removed by running the display at 70hz. I had no issues getting a picture with my CRT monitor, but 640x480@70Hz, 800x600@70Hz and 1024x768@70hz are non-standard display modes.
