This should fix Nascar performance problems.

The per byte mem write detection, instead of per block, is turned on only for games that need it (Tomb Raider 1 and Whiplash). It now uses a custom bitset with a fast ranged fil, so there isn't one or more function calls per byte, just one for the entire range and it is a lot faster. I had stability issues with CR so it's not enabled for all DOS games anymore.

i see you still don't read your status window 😉

It was at 63 MB, lowered it to 31 and I no longer get the warning.

31 MB. nascar 2/1999r 30 fps with instability.

there is another new warning
delete the .conf so it recreates and read 😉

anyway:
high fps is back in nascar
high mem problems are still there - gfx starts to corrupt and crushes

Those are wrapper bugs related to unknown and unimplemented commands. I will deal with all of them throughout the week.

Ef2000 appeared to correctly detect 48mb of ram and start up despite the warnings. OK the game doesn't actually run, but still.

What problems does dosbox have with extended memory?

it doesn't have any problems. Some older games that were never tested on more modern computers may have problems. Just like every game may have problems on computers released later after game was released.
I think verite games shouldn't have any problems as they are from the times there already were computers with such amounts of ram and i guess they were tested on them.

i guess you still haven't tried that:
"there is another new warning

there is a priorities warning

No warning. I did tweak the default priorities back to higher, normal. On my machine, higher, higher works best.

BTW I'm working on speeding up command buffer processing. Got it to work on every machine reliably with CR (except for ALT+X mode), but RMV didn't render anything and Whiplash ran in slow mo. I did this by capturing the dosbox streamed command data and buffering it and then slowly issuing it in another thread to RReady. CR worked really well on a dual core Haswell Pentium/HD4000, Sandy Bridge i7 2600 HD2000 (very slowly) and my dev machine.

Issuing the commands as the DMA stream's received is what kills it. Oddly enough that's how actual hardware worked and I'm sure it wasn't instantaneous.

[EDIT] Oh and I got CR's menus running pretty quickly. I'll do a release when I have sort out the issue performance problems.

Should improve performance, reduce CPU load and be a bit more stable in Nascar 2. ICR2/CR2 high quality textures disappearing textures should be fine now with high detail mirrors. The sky still disappears with low mirrors. Nascar 2 should be stable, Nascar 1999 not so much (both with messed up displays).

[EDIT] and CR2's menus should be much faster. That applies to pretty much anything with a menu (V_FIFO_ MEM_WRITE_SPRITE/VL_MemWriteSprite().

Ok Nascar 2 might not be stable after all.
🙁

cr menus are the same - first one a bit laggy, second laggy more, last one least laggy
nascar 2 menus same too - first two are fine, last one laggy mouse

I noticed an improvement, I et around 8 fps in the main menu. It's responsive but a little slow.

How about performance? I'm trying to figure out the nascar crash, some thing's going horribly wrong there and I suspect random crashing is also tied to that.

If you hold down up or down in the menu does the highlight move around reasonably well?

Not sure, some menus had 3-4, others 6. The end credits gets 14.

it is fast 30fps when i use cart.exe or indycar.exe without fifo parameter

otherwise it is about 6fps on the first menu just like before
it is responsive, but slightly laggy, nothing changed from before

btw descent 2 allows getting to the game now, i can play (black screen though all the time) (got rready watermark during game)
ef2000 shows something in game

Lots of things appear broken now. Texture's loads seem messed up.
