Question for chef's, regarding possible fix for landscape performance

[bast525]

I know some people have not noticed this, for those who have, you know exactly what I'm talking about. For those who want to know, load any app that has animations of any kind, that can work in both portrait and landscape, and notice how much less smooth animations are in landscape. Notice how the horizontal sync seems to be off in landscape (visible tearing even at smooth frame rate), yet they play perfectly in portrait. Load a benchmark app that can render/measure 2d performance in portrait and landscape and watch how much lower is in landscape (SK Tools' bitmap draw test is a perfect one for this... 30% slower performance in landscape!).

I love most things about this phone, and with some of the great custom roms available here, it has become 500% better than it was out of the box in overall performance.... but this landscape issue persists.

Do any of you chef's or XIP-tweaking types forsee the possibilty of ever fixing this issue? I know a lot of people think that this is a driver issue, but that seems odd to me for a driver to work perfectly fine one way and totally horrible the other. I have poured thru the registry looking for things like vsync and rotation settings for hours but to no avail. Is there any chance that some of you chef's would be willing to look at settings "behind the scenes" and see if there is anything that can affect this?

I can only speak for myself when I say that I would happily make a very generous donation if anyone out there could get this fixed. I'm also willing to guinea pig anything on my phone if a chef needed someone to test stuff.

I can't be the only person who is incredibly annoyed by this issue!

I am almost certain that part of the issue lies in the HTC Video drivers that have been a point of complaint with every model they have ever released...

Part of the landscape issue is that the unit resizes the video up to full screen (which requires more graphics horsepower). The larger the picture the more horsepower you need. In Portrait your only using maybe 2/3rds of the screen. In Landscape your using it all...

In this day and age no unit should be crippled by bad video performance...
Quallcomm or HTC (who uses them) should really look at redesigning the video systems in their units.

Much like TF3D their units always seem to be incomplete in some way or another.

I dont think thats it. I see this in web browsing, which uses the same amount of screen real estate either way. I also see it ok that SK tools test, which draws the same size bitmap in either orientation as well.

There was a ROM put out by Da-G over on XDA that a few people said fixed the issue. Da-G said it was a newer driver, but the ROM was only for the GSM AT&T fuze. He tried to give me the ddi.dll, but my phone wouldnt boot past the ROM/radio version with that dll.

I did try the LG Incite ddi.dll, which my phone WOULD boot with, and I saw a roughly 10% improvement on some graphics benchmarks, however this ddi.dll broke some apps like the YouTube app and PocketNester. My eyes got wide when I saw the improvement on the benchmark man... I really thought I'd stubled on to something. However, even with that ddi.dll, performance was markedly worse in landscape mode.... So something tells me ddi.dll is not the answer...

No one? No one at all?? I'm surprised... I know a lot of the chef's here are very active and usually very cool guys to talk to (I'm talkin to you, Scrosler and FormerPalm!). No one wants to look or comment on this subject? Is there really no hope for this issue?

[Asphyx]

Bast, I do hope your right....

I'm not a phone tech I'm a video engineer for HD Production company so my reply is more of a bump than a help...

The machine does appear to be working harder in landscape than in portrait.

I'm gonna subscribe hoping you guys come up with an answer...

[bast525]

maybe there is hope for new drivers from the Rhodium/Touch Pro 2?

[bast525]

bump for updates? now that some rhodium roms are floating around?

Honestly guys, I would PM Juicy47 because he's been awesome at tweaking the filesystem. Just by my observations, alot of it seems to have to do with the caching by the file system too. If you read his thread, Juicy 5, uses the Fuze sys base that uses an overhauled filesystem structure.

Landscape is really snappy and he made some rocking improvements to Camera & the Fullscreen Player. It plays and records really smooth now.

Check his changelog, lots of new stuff. ------edit: (oh yeah, your right! the newer one is from the FUZE)

Juicy47 would be the man to talk to about this. He is tops when it comes to File System as said. Some Chefs display a focus on APPS and visually standing out.

Juicy has so much good in 5.0 its ridiculous. It blows 21014 Juicy 4.7 out of the water. Also note, that the landscape performance as well as video performance in Juicy is the best ive ever seen, i can't stress this enough.

He is using 20771 which is Fuze based
