unther , I never understood how those built-in scalers worked. Can you explain, perhaps? Unfortunately, I don't have any real understanding of how they work either (or really any familiarity with the dosbox code base). I just used the existing normalNx scalers as a template to create a normal4x5y …

This is an excellent addition for those on single-Ghz systems (early Pentium 3's, Rpi3, etc..) to get as close to crisp pixels on modern displays. Thank you! Not a problem, but just to clarify for others, because 'normal4x5y' is a fixed scaler, it's only optimal for running 320x200 games on a …

Ant, would you expect your 5x5y algorithm to perform similarly to normal5x? I know it doesn't, but I do not understand the implementation of the normal n x scalers so I cannot tell you now whence the difference. I will think about it. Ant_222, just a follow-up to our performance discussion a year …

Whosoever shall desire to try the test on his own machine, let him download the source from the attachment to this post. Ant, I'm getting the following results with your test program running on a Raspberry Pi 3 (Quad-core ARM Cortex-A7 @ 1.2 GHz) -O0: Scaling 320x200 -> 1600x1200 at 24 fps. -O1: …

Unther, Does your build solve the issue mentioned here? http://www.vogons.org/viewtopic.php?f=41&t=49160&start=320#p592089 krcroft, unfortunately the wolf3d menu fade effect is still causing audio stutter on my build when using output=surfacepp. The game itself seems to run fine though as long as …

Note: if anyone else wants to try this on a Raspberry Pi 3 using the RetroPie image, I compiled as follows: 1. install the necessary libraries and development tools: sudo apt-get install libsdl1.2-dev libsdl-net1.2-dev libsdl-sound1.2-dev libasound2-dev libpng12-dev automake autoconf zlib1g-dev …

Hi Ant, I just tried this patch out today and it looks great - thanks for making this. After testing on my desktop, I wanted to get it running on my Raspberry Pi 3 (RPI3). However, I ran into compiling problems related to OpenGL calls. From what I understand, the RPI3 GPU driver doesn't support …
