Re: Old+Modern videocards pure DOS performance- which one is fastest?, need your numbers + analysis, 320x200 to 1600x1200!

Typically even Geforce 6/7 cards do not list 1600x1200 but 1280x1024 as the biggest supported resolution. Also some cards (e.g. my Inno3D Geforce 6600 AGP) do not list even 1280x1024 as a supported resolution right after boot in DOS, but it lists 1280x1024 after you booted Windows and drivers …

I wonder if its possible somehow on software side fix, that 1600x1200 is not available on some modern cards, or its rom thing? Yes, it's a 'ROM thing' in many cases. You can use the attached VESAINFO utility to list all supported VESA modes. (type 'VESAINFO /l |more'). VESAINFO.zip Typically even …

Update: Navratil System info reports with different cards, different page sizes? Could it have some performance effect too? Its bigger or smaller better? You should interpret this info in its context: Namely 'Current video Mode: 3' and 'Video Segment address: B800h' show that this info refers to …

I think protected mode programming for DOS was more or less limited to Assembler, C and C++. Not entirely true, even the old Turbo/Borland Pascal 7 compiler supported 286+ 16-bit protected mode DOS target. Also Free Pascal compiler has 386+ 32-bit protected mode support for DOS for more than 2 …

However in most cases the performance (and thus frame rate) will be increased, Of course, in theory page flipping should be always faster, unless drawing to video memory directly is much slower than to system memory. Page flipping saves an unnecessary Bit Block Transfer from system memory to video …

Of course more results are always better since they can show a more detailed picture, but it means more work for you/for your contributors. Anyway here's a detailed description about the vid_nopageflip 1 option: vid_nopageflip This variable toggles the use of page-flipping during supported video …
