So the original issue was the inability to open more than 2 "Heavy" sites before Opera stop loading anymore in new tabs. This has been solved on my device thanks to c4Lvin in post "11"


I thought I could also share a couple of registry settings that improved my browsing experience a great deal (cab attached):


Increase Scrolling FPS
I changed the following key to:
[HKEY_LOCAL_MACHINE\Software\Opera\Info]
PanFps=50

Increase Zooming FPS
[HKEY_LOCAL_MACHINE\Software\Opera\Info]
ZoomFps=50

These two above make a world of difference in smoothness of both scrolling and zooming on my device. Do not enter a value higher than 50 or it will not take effect (at least it did not on my HD2)

Also,

Lower Default Zoom (Really takes advantage of the HD2 beautiful screen)
[HKEY_LOCAL_MACHINE\Software\Opera\Prefs\Adaptative Zoom]
Default Zoom=100


Edit:
OK guys, I have created a cab that "Should" work. I tested it on my HD2 and it worked, but, INSTALL AT OWN RISK

What the cab should do is introduce (change existent values to) the following:

HKLM\Software\Opera\Info\PanFps=50
HKLM\Software\Opera\Info\ZoomFps=50

And it will also create an Opera_Smooth_log.txt file under \My Documents\ (Yes Phone Memory, you can delete it)

Enjoy

Thanks for this, made Opera browser even better. Hopefully when Opera Mobile 10 comes out they can include all the HD2 tweaks for it as well.

Great! works fine...thnx

Boy this has got to be the absolute best tweak ever! I can't believe nobody else had this earlier (at least I wasn't aware of it). It was never mentioned on the tweaks section. Your few reg tweaks just made the HD2 scroll SO SMOOTH (similar to IE). I totally agree with you on 2+ tabs on heavy sites. I can't ever load my ebay pages and engadget without closing one or the other which is a shame. I noticed it's not the opera's program itself but I think when the chef cooks the rom, some will open more and some opens less. If you see under the taskmgr (manager) that depending on what ROM, it maxes out at about 3.5-3.7MB. Some ROMS are 4MB+ then it won't open anymore pages without you closing one. Believe me I've looked for MANY MANY tweaks to make this really a multitasking phone. I can careless about SMS problems and facebook apps (sorry If I offended anyone). The web is what everyone needs. So opening 2 tabs of hardcore information super highway just won't cut it for me. Let me know when you find something new!!! I also enable TURBO MODE which seem to help it abit. All cooked ROMS don't have it enabled, not sure why.

Good luck! I'll be checking this thread quite often!

I just went under the registry and saw something under HKLM/SOFTWARE/OPERA/MEMORYLIMITS which can play an important part on this...gonna try to fiddle around with it now. BE BACK!

Thanks for your tweaks. I especially like the default zoom tweak. I was looking for this, but postponed it constantly, because I don't like the hassle of blindly changing the reg. till I get what I'm looking for.

Thanks again. Keep those reg. tweaks coming!

Nice tweak. There is a noticible improvement in the fluidity of panning and zooming (with pinch).

OK, i just finished tinkering with the registry and I can open up a few more tabs COMPLETELY without any errors. Pages include the webpages you mentioned, www.facebook.com (logged in and non mobile), www.lifehacker.com (non-mobile), engadget.com (full page), my ebay selling page with over 200 + items and thumbs, www.coasttocoastam.com...then i checked my CPU usage and at times it's over 50% and then up to 95%..it goes back down..so at least it's alot of improvement. Not alot of people use that many tabs and especially these heavy pages but I do need some of them. I think it works great. It hasn't crashed once so far. Need to further test it.

Really great tweaks!.. I wonder why HTC didn't include these in the first place...oh wait..this is HTC we're talking ..the same guys that couldn't work out how SMS works..

Just a question.. are those values in hexadecimal or decimal only???
