I've got a very general question. I've downloaded the latest ECE build and launched it on my laptop with Win XP and Pentium 4m 2400MHZ. No settings were changed in config file. And still in simple DOOM I'm getting almost 100% CPU load. A 2003 year cpu is not enough to play DOOM via emulation?

Tried surface and ddraw, no change.

DOS games did not throttle their CPU usage because it was mostly useless back then. The real question is: Is DOOM running smoothly or not?

And without native code generation via the dynamic-x86 core, that is, full software emulation, I would expect a Pentium 4 to be a tad too slow indeed.

On a 2003 pc if you want to play doom on xp then you should use a port, chocolate for vanilla. If you don't want to use a port or boot to dos then vdmsound with ntvdm will work.

i have a suggestion for ECE for crt and other shaders, which what im using to remember if i forget.

# glshader: A new package of CRT Screen shaders for DOSBox ECE, DOSBox currently includes two OpenGL outputs (opengl and openglnb).
# opengl enables bilinear filtering of the input source, while openglnb disables bilinear filtering and uses nearest neighbour scaling instead.
# openglnb has the same effect as the the filter_linear0 setting in RetroArch .glslp shader preset files.
# opengl is equivalent to the setting filter_linear0 = true, while openglnb is equivalent to filter_linear0 = false
# An example: fakelottes for game resolutions up to 640x480, easymode for game resolutions over 640x480, geom as a 'jack of all trades' for all resolutions.
# For more information, check https://github.com/tyrells/dosbox-svn-shaders and https://krystof.io/dosbox-shaders-comparison- … s-retro-gaming/
# Example values: crt/crt-aperture.glsl (uses Openglnb), crt/crt-easymode.glsl (openglnb), crt/crt-lottes-fast.glsl(opengl), crt/crt-nes-mini.glsl(opengl/openglnb), interpolation/pixel_perfect.glsl(openglnb).

PSA: yesterplay.net seems to be down

Seems that I could enter the website (the link from Yesterplay80's sig) but unable to download the files. I got a 504 error in the place where the files can be downloaded after waiting a time.

Edit: Website is online once again with the files available to be downloaded.

A lot of other DOSBox builds are getting composite CGA modes perfected. Like DOSBox-X, DOSBox Optionals, and DOSBox Staging. In PCJr and Tandy modes we have 3-voice music with composite 16 color graphics.

I really love playing my old CGA games in full color. I hope DOSBox ECE adds this feature soon.
