wont' refresh at the viewer side. w/ directx v9.0c installed

[tony.yun]

hi. i'm new to pchelpware and i think this tool would be quite useful and important for me. however, during the my trial i found the screen shown at the viewer doesnt' refresh correctly and i can say that it was freezed. i checked with my computer, the directx v9.0c is installed and running with no problem. however, i aware that the "directdraw acceleration" was unavaiable, does it realted to the issue?

please advise. any comment would be thankful.

For PHW-viewer works with the display acceleration advantage, your computer must be installed with DirectX 9 (or later), AND YOUR display card must support DX9 too -- having DX9 installed doesn't mean your display card having real DX9 capability.

If the "directdraw acceleration" is unavaiable, the viewer will switch to GDI mode automatically (i.e. not using the DirectX feature), then the screen refresh will much degrade. However, even that it should not be as worse as freezed ((in my experience)).

What is your connection condition? (through internet? via repeater?)
Is the display card a very old model? What is the driver verion shown in dxdiag?

thanks for your reply. actually, my viewer pc is very old and it is P3 configuration. i guess the VDO adapter doesnt' fully support the directx v9.0c as well. however, is there any way to improve the quality of display remote computer other than upgrade my pc? thanks.

ar... sorry. i missed the connection setting of my own. it is very simple. my viewer is running on the public ip and clients (server) were running behind NAT. or I did tried on public ip, however, both were same.

I had used a old computer, equipped with a Ati Rage IIc (no directdraw acceleration too) to run viewer, I got slow screen refresh, but not as worse as your situation.

If the bottle neck is the viewer pc, you may try to select "Mid" or "Low" quality to see any improvement.

Other than this, you should notice:
1 Is the server pc fast enough? It need to do encryption job that will spend a lot of CPU power.
2. So your connection is via internet. What is condition during your test? Some ISP just provides a relative slow updown speed. Some ISP provides services to customers sharing a bandwidth so speed may vary from time to time.
3. If using repeater (especially not your own), the connection speed will be much degrade too.

thanks for your suggestion. in fact, my pc is quite slow and i guess it would be better if the encryption is possible to be turn-off. but i dont' know how.

my connection is 3m broadband (viewer) and few tests carried out to couple of my friends which connected to different ISP. however, all results are the same.

** since i cant' fixed this problem, then i tried UVNC_SC, of which might able to help me (specally for my old pc). when i test it, it works as my expected. result in good and fast. now, i'm wornding why the pchelpware cant' performing as i'm expected. trying to chellanging the problem.

Ack your your test result.
However, the encryption in PcHelpWare is hard coded and can't be disabled.
In contrast, SC itself doesn't have encryption, and usually operate with plugin if you want it. May be this is the cause of the slow response.
Have you checked the CPU/RAM usage with Windows Task Manger on the server & viewer?

[tony.yun]

thanks yy. as of my observation, the cpu was running nearly 100% while operating the viewer process. i'm agree to your point, and also i just carried out another simulation on the faster pc, however result was same but different in cpu utilization. in the better performance computer, cpu usage only not higher than 25% while operating the viewer.

anyway, any other sugggestion for shooting the problem? you're really my good adviser.

[YY]

Does the "better pc" have DX9 installed?
Is the display card a real DX9-support? For this issue, you can check the driver version & DDI version with dxdiag. The DDI version s/b 9 (or higher) for a real DX9 supported card.

I still not sure if you were running a direct connection, or via repeater. Anyway, I will suggest to run a direct connection in LAN, so that eliminating the internet speed problem, and see how fast/slow can PHW run on your hardware.

[tony.yun]

thanks. let me try.
