Eighty One with the WRX graphics option enabled and 32k ram runs properly (with the advanced video effects enabled).
Obviously I'm pushing it to the limit, I wouldn't be surprised if the program crashes on a real zx81.

384 rows super HRG
Can anybody test this one ?
It should work in WRX mode with 32K ram.
You should see 2 lines, one will appear in standard resolution, the other one sould be more refined.
The resolution should be 256x384 interlaced.

Re: Enhanced ARX True High Resolution Display Driver
I've noticed that ARX graphics driver is still unstable when used in 64 rows mode if the break detection is excluded. I'm investigating. In attachment a bouncing balls demo in 64rows mode (runs much faster than on a full graphics page). The ARX version incorporates the BREAK detection as a workaroun...

Re: Enhanced ARX True High Resolution Display Driver
All, I've updated the libraries already in the Z88DK tree. On any problem I can get back to it and try to tune it better. The sampler archive I've posted some time ago is still very close to the current tuning, if something looks wrong please check the latest test cases before complaining. I can obv...

Re: Enhanced ARX True High Resolution Display Driver
The fractal program is cool but very slow. It probably takes some day to complete on a regular zx81, I'm tuning it to restrict the execution time a bit.

Re: Enhanced ARX True High Resolution Display Driver
I think the best compromise is to cycle between 4 frames, a first one (light gray) appearing only 1 time and the second one (dark gray) being displayed 3 times (thus a white frame interposed only one time). The result seems plausible, observing it on EO, (this is the best screenshot I could take, th...

Re: Enhanced ARX True High Resolution Display Driver
More about the gray library, I have 3 possibilities,: the current driver shows a first frame 2 times, a second one only for 1 time. This is in theory correct because the picture would allow a higher persistence to one of the two allowing a dark gray and a light gray. By the way the 2 frames in a ras...

Re: Enhanced ARX True High Resolution Display Driver
Right, this makes a difference ..both?
..in the meantime I found a way to work this out:
I'm afraid it won't be healthy for your eyes !
I've already put the latest driver version online, I think it is already better than the previous ones.
