Unofficial fVDI driver can be found here:

16 bits driver
EXTERNAL LINK 
32 bits driver
EXTERNAL LINK 
compare to previous version 16 bits version copy bloc is  around 2.2 time faster than original one and 32 bits around 32% faster than first version I made.

For 16 bits I have compare 32 bits version to 16 bits one with Kronos and discover MB/sec was around the half for 16 bits version, so same number of pixel 32 bits  or 16 bits driver! This is only a simple copy in memory. Reason was simple copy was done 16 bits by 16 bits rather 32, this was quite easy to do a copy in 32 bits. For sure it could be probably far faster using 68080 potential.

On X12 core I found around bloc copy is around 170MB/sec, it not use any possible parralel instruction, what could we expect with better code ?

There is some other easy improvement to do for 16 bits drivers, I will look at it next week.

There is no C compiler able to compil for 68080 using long long 64 bits version ?
 

There is VASM that said, with 080 support, also available for TOS.

However, since the 080 have fuse features, a 64bits copy can be done transparentely using legacy code with 2 consequent move.l, like this :
 
  Loop:
  move.l (Ax)+,(Ay)+
  move.l (Ax)+,(Ay)+
  subq.l #1,Dn
  bne.s  Loop
 
  Or :
  move.l Dn,(Ax)+
  move.l Dn,(Ax)+
 
  Or :
  move.l #Imm,(Ax)+
  move.l #Imm,(Ax)+
 

saga32.sys
    - fix xor operation bug
    - some speed up on fill and line draw

saga16.sys
    - Speed up 20 - 30% on some fill and line redraw

There is probably better to do but I not want spend too much time for this drivers, compare with CT63 100Mhz and supervidel except text redraw and copy from video memory to video memory far faster on CT63 other are quite same or a bit faster in 16 bits.

I have used gitub version from Vincent

Sorry, let me some time to fix issue.

Hello     Today I have updated 16 bit driver only     EXTERNAL LINK        - Now hardware mouse supported (developpement from Otto driver) :   EXTERNAL LINK - very cool update that speed up in some case.     - Speedup copy block of around +50% compare to previous version thanks mixing 2 GCC compiler most with GCC 4.6.4 and for 2 functions optimized with GCC 2.95.3 far more efficient on some simple loop.     - Some very small speed  up on filling (some % only)     Have fun     Olivier

Now work on 32 bits driver!
