There're other changes in that build. Hopefully won't break anything.

yes whiplash intro in dma=0 has jerky sound

it looks it's caused by something else, although it doesn't happen on 2 cores 🤣
---------

as for the priorities: it looks its either sound or gfx:
- so higher dosbox gives clear sound,
- higher dosclient gives less laggy picture (it looks picture gets more and more laggy and than makes a sudden jump to real time)

Need some way to get the CPU load down without impacting performance. I can't get ICR2 to run on my Sandy Bridge based machine. It shows a single frame and drops out. This is an i7 with HD2000. The logs indicate garbage in the DMA stream.

My attempts to block Dosbox's virtual CPU mem access while Rendition reads the DMA pointers haven't worked yet.

I'm putting the instability/performance on hold and focusing on functionality for now. This is taking a lot of time.

Is this with a discrete GPU?

with normal gfx card

Since dosclient is gpl 2.0, I guess I can use alternate structures to communicate instead of just named pipes or sockets. Some of this stuff would be easier with shared memory. It would also have a much lower overhead, less cpu and more performance.

Pipes are relatively low overhead though.

Nightly snapshot:

CPU load lowered, instability fixed (thanks @ripsaw-8080 for pointing out how to handle thread safe DMA in Dosbox).

There may be rendering defects (Whiplash menus in DMA mode has issues, [ALT+X] in ICR2 also has audio sync and framerate issues. The reported frame rate is in the hundreds, but the actual rate is in the 40s. The car can be controlled just fine though, which is weird).

There may be more problems. Tomb Raider also may have new issues with the menus when existing a game. The background image may render and there may be some instability.

[EDIT]This now runs on my Sandy Bridge i7 with HD2000 at 5 fps instead of crashing after the second frame. Once again many thanks @ripsaw-8080.

And here is a gratuitous demo of Rebel Moon:

No graphics fixes, just the built-in demo in its entirely.

task manager - details:
"System Idle process" takes 40-50% of total cpu usage

cart racing is extremely lagged
whiplash is 1fps

meanwhile got this:
Rebel Moon 2: Rebel Moon Rising 😀

Wow!

How'd you get that going?

bigger wow

just copied level files and missing files from gif, textures and SCRNS

That is a bigger wow!

though i guess the new texture files may be corrupted when they appear somewhere on later levels
or even on this level as it was loading them

I guess it's not officially supported.

I've disabled the thread safety code:

Could you see if it performs any better? I did manage to get the CPU load down to20% of a 16-thread CPU.

only thing that has changed now is cpu usage jumped from 50% to 80%
cart racing still unplayable
though it got responsive after some time, cannot reproduce it cause it is crushing though

you can test on 4 cores without rebooting by starting command line and typing
start /affinity F rlauncher.exe

chart for more/less cores options are here
https://learn.microsoft.com/en-us/archive/blo … pu-affinity-set

you can verify which cores app uses while running in task manager ->details - right click on app - set affinity
you can change it live there
you can check/change priority there too

you can reduce cpu MHz speed in control panel - power options - power saver (between 50%-100%) (less than 50% will be still 50%)
