Re: Peformance on Linux x86 vs x86_64?

"Normal" is always the normal core (interpreter/slow). "Dynamic" depends if it was compiled with dyn_x86 (32-bit x86 builds only) or dynrec (all other platforms).

Are you able to build DOSBox yourself to test patches that eliminate the need for execheap permission?
Re: Peformance on Linux x86 vs x86_64?

Basically at the moment it boils down to DOSBox having two different high-performance cores: dyn_x86 and dynrec. Dyn_x86 is very fast but currently only supports 32-bit x86. Dynrec is slower but still much faster than normal/full core, and supports 32/64-bit x86, ARM, MIPS, etc. Dyn_x86 will …

Do coders in UNIXland actually use UTF-8 strings in memory? I never handled those, only UTF-16/32. A UTF-8 file will be read into memory as UTF-16 or (preferably) UTF-32. The process is reversed when saving the file. Up until about 6 years ago the android NDK didn't support wide chars - wchar_t …

I think you're missing the point here. I'm not. Getting the number of characters is not what you want if you need to allocate storage for a string. Using _tcslen/mbslen on a UTF-8 string for that purpose would be a mistake, so it is obviously not "the only semantically meaningful type of strlen". …

Also, if I were to just interpret the string as UTF-8, it would also break, because these characters would be interpreted as multi-byte sequences, since their value is > 127 (eg a strlen() for UTF-8 would give different results than a strlen() for codepage 850). This isn't true because strlen() …

So, if you have a >2TB drive, you can't describe the size of a single partition with a 32-bit LBA field. Ergo, with an MBR table, you can have a max part size of 2TB. You can have 2x 2TB partitions on a 4TB disk, but that's pretty much the end of the road. Your only alternatives are to use GPT or …

How hard can it be to set a GNU make flag equivalent in VS... uh. Well hold up there - a make flag isn't the same thing as a preprocessor definition. Visual Studio is a compiler/editor, GNU make is a build system so they perform different functions. The VS equivalent to make would be nmake which …

It means it's already being defined somewhere else, in a global header file or something similar.

you don't need 300 MBits per second bandwidth. The maximum bitrate for Blu-ray Disc movies is 48 mbps. that and a PCI bus is 133 megabytes per second (300 mega bits = 37.5 Mega Bytes) Again, the Blu-ray bitrate is only for the compressed data - the decoder card has to send the decoded raw frames …

Re: VIDEO Patch for pixel-perfect scaling (SDL1)
Posted on 2019-09-04, 11:10
openglnb is exactly the same as opengl but with nearest neighbour (i.e. integer scaling) instead of bilinear filtering. Not sure what your definition of "integer scaling" is, but duplicating rows/columns is what it does when enlarging images.

Given whole-integer scaling is straight forward, more accurate on modern high-DPI displays (versus the existing double-every Nth line method), can be implemented along side the current scaling methods without influence on their performance or function, and doesn't require exotic underlying …

The point was if you're using a 64-bit version it will be much slower than 32-bit.
