Joined Jun 17, Messages 6, I had a Realvnc server running on a xp machine I was using for my company. Long story short my HD failed, got a new drive and installed win7. Now the vnc server is super sluggish. Any action on the server takes a hell of a long time and my coworkers cant work with it being so slow.
When I had xp installed the server ran like a champ. In win7 I turned off aero and I think that helped a tiny bit but no where near enough. Im kind of stuck between a rock and a hard spot. My coworkers are not computer people so I have to make this as easy.
Realvnc viewer is a single click operation, kind of need to stay with something like that. Id like to stay with realvnc, payed for it, dont want to have to pay for another program when this one "should" work. Is there anything I can do to speed this up? The pc is pretty good i7, 6gigs a ram with 1 real monitor and 3 vga dummies ones running off of ATI HD.
Never had an issue with the vga dummy till now. Joined Jan 20, Messages 18, You need to change the number of colors that get transmitted. Try something like 16bit or colors. It has been awhile so i forgot exactly how to do it but that may help. Also you should change the resolution of the server, make sure it is not like x Joined Aug 28, Messages 2, Along the same lines: no high-jack intended.
I use UltraVNC. Tried all such options as suggested above, no luck. Switched to a Base network switch and cables, with no change in performance. My network files are 10X faster but my remote viewing is still crap. Yes I have selected various configs, including the highest beta speed, but it is still dirt slow. What to do? Don't mind switching software, but what is close to a VR machine?
I want speed. Can do with shit like 8-bit colour ect.. I need the network VR solution in RT. Ok I think i remember now how I solved this. Give it a try. Dion 2[H]4U. Joined Oct 2, Messages 3, Dapperdan what RealVNC server are you using.. The Service? Fix broken screen color with vnc4server in 32 bit color depth. Fix broken mouse cursor color in 16 bit color depth. Fix corruption along mouse cursor trajectory Fix broken background color in 24 bit color depth vncviewer. Were possible, functions are replaced by there security enhanced counterpart.
Viewer: -Fix overrun crash -Timeout reconnect fix -Closing no reconnect fix -Auto refresh after idle Update jpeg lib. Long hostnames etc…. Instead of using the password as part of the encryption, we now check the password insite the encryption by the server. This allow the server to balcklist servers after x fault password.
No protection against Brute force password hacking. And doesn't ask to reject the connection. Files: ultravnc X64 setup.
I've also heard really good things about ZeroRemote , but never tested it. It appears that TrueRemote is its successor. If you're trying to watch video across a LAN, the fastest solution in terms of sheer screen-drawing speed is probably Radmin. This is by design so that VNC doesn't have to "understand" what the remote client is trying to display.
RDP actually does, so it can take shortcuts and render images faster. RDP tells the other end, for example, "client opened a window at this location" instead of sending the bitmap data representing the screen change. There are "terminal server" hacks out there that will add RDP capability to the versions of Windows that don't feature them, but I don't officially recommend them and you use these at your own risk.
Things you can do to improve VNC performance, however, include lowering the display depth to 8 bits, lowering the resolution of the client screen, and using client-side bitmap caching. That means VNC has to ship less data on the wire and you'll experience better performance but it won't look pretty. The magic comes with changing the connection settings. After starting the viewer, go to "Connection Options", disable "Auto select best settings", enable "Tight" and lower the "Jpeg" to lower quality, if needed works well.
That is the only way I know of of gting Full Colors with decent performance. You will get several fps afterwards, enough to get a fast slideshow on a full screen movie enough for everything I am doing, including remote development, for real movie watching too slow and also there is no audio.
Basically, just about everything on the left. It's free and works well. You may also try TeamViewer, it's free for non-commercial use and was fairly fast for me. I've not tested it on HD video though. Sign up to join this community. The best answers are voted up and rise to the top.

Improve this answer. Yup, doesn't work on non-Pro versions, although there's a workaround I suppose. Ah, I should have stipulated what I did in my edit just now! Edited my answer to include remote assistance. Have you looked at Remote Assistance? I use it occasionally and it works great. Show 7 more comments. There are several constraints here: Strong compression needs a lot of CPU power.
For example encoding a 90 minutes movie in H. Usually such strong compression is unsuitable for real-time applications like remote control. Less strong compression in turn will require more network bandwidth which might become an issue on low-bandwidth connections like the internet. Some of them are optimized for small bandwidth, some for good image quality and some for low latency. This touches another aspect of remote control.
Since the service is interactive latency matters you don't want to see the reaction to a mouse click just after 5 minutes of encoding. Try to reduce the amount of screen changes on your host machine. For example try disabling Windows desktop effects, animations etc. This saves bandwitdth as only changed parts of the screen are transferred over network. Try disabling further visual effects on the host like transparency.
So disabling Aero transparency and desktop effects really speed up remote control experience. Most remote control tools even allow to disable such effects automatically on connect e. Same applies to background pictures.
Try using uni-colored background setting instead of HD pictures. SkyBeam SkyBeam 3, 15 15 silver badges 16 16 bronze badges. Nice try but totally wrong, neither the CPU load nor the network usage is anyway high. With addons like Single Click SC your customers don't even have to pre-install software or execute complex procedures to get remote helpdesk support. We are a small team of highly motivated and cool people :- Our goal is to make the more powerful, user-friendly and no-brainer free Remote Control software available.
UltraVNC is a powerful, easy to use and free - remote pc access softwares - that can display the screen of another computer via internet or network on your own screen. The program allows you to use your mouse and keyboard to control the other PC remotely.
The Aero effects seems to really slow down any kind of remote desktop/VNC. I always used to use RealVNC/TightVNC, then Remote Desktop (RDP). marn.copljo.info › Windows › Windows 7. VNC has gotten a bit slower over the years but works well and always a backup I haven't had too much luck with Ultra VNC and Windows 7.
