[Freedos-user] Odd behaviour involving mouse
Hi, I'm an engineer and a user of DESI-III, a professional-quality freeware CAD from Belgium, with which I draw mechanical parts for a product I'm developing. Since I started using FreeDOS in 2007 I noticed that it was taking longer for DESI-III to refresh the screen -- an important point for CAD software, because we must zoom in and out all the time. Then a few days ago I noticed that, if the mouse is moved, the screen refreshes much faster. For instance, the drawing I'm currently working on would take 11 seconds to refresh, whereas if the mouse is slightly pushed in any direction while the image is appearing on the screen, the process takes only 2 seconds, i.e., it gets *five* times faster. Then last night I decided to run Desi-III under MS-DOS. I reinstalled it in a spare hard drive, and it turned out that the speed difference is huge. Under MS-DOS the screen redraws so fast that couldn't measure the time. It must be something below 0.2 seconds for that same drawing, so we are talking about a factor of *fifty* here. I had already written to Desi-III's author Hugo Marin about this. He answered: It is a surprisingly story you are telling, because IMHO it has nothing to do with DESI-III but with your configuration. [..] DESI-III only calls the mouse on demand, it doesn't need to call the mouse driver when the screen is refreshed someway or an other, it only calls the mouse when it needs displacements or a button detection else the mouse is left alone. Back to FreeDOS, I did some simple testing, such as changing the mouse driver from CTMouse to Logitech, and changing the mouse itself, with no results. If there is any additional test that I could do, please let me know, and I'll report back ... after Christmas :-) Desi-III can be downloaded from: http://users.telenet.be/desi-iii Regards, Marcos Marcos Favero Florence de Barros Sao Paulo, Brazil 55-19-3231-8194 fav...@mpcnet.com.br -- This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
Re: [Freedos-user] Odd behaviour involving mouse
I don't know if this relates or not. I use Freedos in a dosemu emulator in Linux. In that environment, arachne won't update a screen unless I hold down a moust button, or a shift key (or some key). Have you tried holding down a shift key to see if your CAD then updates the screen faster? --- On Tue, 12/22/09, Marcos Favero Florence de Barros fav...@mpcnet.com.br wrote: From: Marcos Favero Florence de Barros fav...@mpcnet.com.br Subject: [Freedos-user] Odd behaviour involving mouse To: FreeDOS List freedos-user@lists.sourceforge.net Date: Tuesday, December 22, 2009, 6:13 AM Hi, I'm an engineer and a user of DESI-III, a professional-quality freeware CAD from Belgium, with which I draw mechanical parts for a product I'm developing.

Re: [Freedos-user] Odd behaviour involving mouse
I guess there is one test that could be done... Is it possible do run a test without any mouse driver installed? Of course, only if th SW is capable of keyboard-only operation.

Since I started using FreeDOS in 2007 I noticed that it was taking longer for DESI-III to refresh the screen -- an important point for CAD software, because we must zoom in and out all the time. Nice that someone uses DESI-III with FreeDOS :-) Then last night I decided to run Desi-III under MS-DOS. I reinstalled it in a spare hard drive, and it turned out that the speed difference is huge. Under MS-DOS the screen redraws so fast that couldn't measure the time. It must be something below 0.2 seconds for that same drawing, so we are talking about a factor 50 Back to FreeDOS, I did some simple testing, such as changing the mouse driver from CTMouse to Logitech, and changing the mouse itself, with no results. Very strange ... It is a surprisingly story you are telling, because IMHO it has nothing to do with DESI-III but with your configuration. 1. Try EDR-DOS 2. Reveal what EMM386 you are using (regrettably DESI-III requires EMS IIRC) 3. Other stuff (driver, TSR) present ??? 4. Free more low memory (frustrating low memory wars ... I hate them) or EMS page frame size This is most like related to the low memory hogginess of DESI-III and the EMS usage :-( Of source, porting DESI-III to 32-bit DOS (WATCOM FORTRAN) would be a great thing :-) Is it possible do run a test without any mouse driver installed? Of course, only if th SW is capable of keyboard-only operation. IIRC you can't even exit DESI-III with the keyboard (this is a BUG ...) -- ~~~ wow ~~~ -- This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
