All the games works very good, no degradation spotted.
Tested:
Rebel Moon:
Font need to be fixed, a little lines appears.
Set SPEEDY3D_DMA=0 (buggy graphics)
vsync should be turned off, otherwise high fps drops while located as maximum as possible to wall and moving mouse while directly looking at wall.
music could stop play spontaneously
fps varies fromn 99 to 430
novert.com is recommended to play without moving character forward /backward by mouse
SODA Offroad Racing:
Super Resolution idea - make it serve a super sample antialiasing purpose? to get internal frame as 2x or 4x etc, than downscale it back to chosen resolution by bilinear or bicubic or other method, so it will remove aliasing and distant noise etc.
AA - i use nvidia control panel to enforce AA , i think it also can be a good idea to use it in RReady panel.
Force perspective correct - as experimental option
Force texture filtering - force all unfiltering , game prefered, all filtered (i will use it) .
Disable mipmaps - well i remember i need to do it.
Game crashes - unfortunately game crashes after changing environment a lot like between tropic / desert / etc
Cart Racing / IndyCar Racing 2:
widescreen low fps for me
widescreen patch on non widescreen mode, HUD blinks
sometimes rear mirrors blinks rarely.
game starts with default rear mirror details, would be good to have it at maximum details set in RReady panel.
random weather would be cool to - like starting new race will change day/fog/night environment
icr2 itself needs more raw cpu power under dosbox , you already aware
super resolution sample down with bicubic? so it serves purpose of anti aliasing.
also if possible force texture appearance at more far distance. to hide all flat shaded polygons
rear view mirrors , can't have AA enforced in control panel. the rest geometry have AA forced and its works flawlessly
force texture perspective correction
force texture filtering
sometimes sound produce clicks or gaps to be precise. probably due to low cpu cycles
Force alpha blending over alpha testing, even better to have alpha to coverage technique its way for future as advanced
Possibility to disable LODs for cars
Maybe possibility to load geometry much more far distance than now, it dynamically shows / hides geometry depending your position.
