Another topic…

Hi QLers,

I think we need another topic.

Recently most discussions on ql-users and qlforum were about Rich’s Software Preservation Project and Copyright. Even I have a clear opinion on all that I will not write it down here for two major reasons:
1. English is not my native language and I feel a bit uncomfortable to find 100% the right words. Also to write it down that it clearly expresses what I think my need some considerable amount of time, which I do not have or do not want to spend at the moment (just days before my summer vacation with plenty to do at work and private life).
2. I better spend my QL time with doing QL stuff than to discuss the above.

Last week I started the Windows 10 upgrade job on all my PCs and all the PCs I somehow control.

Last week I documented how our fastest PC in the family was performing QL/E under Windows 8.1 64-bit. There’s a video about that which shows – among other things – how QTop-Index (New PCW benchmarks) and QTop-Demos are performing.

This was before the upgrade to Windows 10 which was done the next day as a fresh installation, not as an in-session update.

Having Windows 10 64-bit on this machine for almost a week now is nice. All runs great, but running QPC2 shows that some QL graphic operations are substantially slower than expected and what counts more, they are much slower than running exactly the same under Windows 8.1. To document this behaviour I made another video.

Watch it carefully and re-test on your rig.

I think that the slow performance of Photo QL, QTop-Index (TEXTSCRN, GRAFSCRN benchmarks) and QTop-Demos (CIRCLE, ELLIPSE, SPACE, WORM demos) is just the symptom not the source of the problem.

It’s not the first PC with this weird QPC2 behaviour. I have seen this on several PCs running Windows 10 but not all. Some are running (fast) as expected. About a year ago I first reported this on qlforum (Fri Jun 05, 2015 8:36 pm), but nobody took up the line on that.

Anyone? Marcel?

QL forever!

P.S. SMSQmulator seems not affected; its performance is comparable when running on the same hardware under various Windows versions (7, 8.x, 10). Using latest QPC2 (v4.04) and SMSQ/E (v3.26) does not better the situation.

Hi Urs,

I have dual-boot Windows 7 and 10 (both 64-bit). I use Windows 7 as production environment and 10 mostly for testing.
I did notice slower performance of QPC on Windows 10. When using my favourite resolution (640x480, upscaled to 1280x960 on the PC display) I got about 1290 on the graphic benchmark. Under Windows 7, I get 1660. When using native QL colours, there seems to be no performance degradation (I get about 1760-1770 under both environments).
I have the impression that QPC2 v4.04 does perform better under Windows 10 than v4.02. The version supplied in the qle directory on The Distribution took minutes to load the picture in 1024x768 high resolution!

cheers, Jan.
