    RadeonSI and Unity performance

    Hi

    So I'm using Mesa+LLVM Git on kernel 4.7.2 with radeon kernel module on a mobile Cape Verde (SI, 512su, 675Mhz, 1GB vram)(i7-3720QM, 16GB ram), and generally the experience is fantastic. Most games run the same as it used to on Catalyst, and some such as Shadow Warrior, Tomb Raider, The Raven and the Metro series run oh so noticeably better. :-)

    But it seems some of my Unity games are noticeably slower than before.
    I used to be able to run War For The Overworld at full HD and good settings smoothly, whereas with RadeonSI it is quite jerky. Even lowest settings is not very smooth.
    The same can be said for Dreamfall Chapters, it is completely unplayable slow, until I disable shadows. Then the frame rate is practically smooth?

    Does anyone have any hints for me to get performance better on Unity games? Any debug info I can provide?

    Heh, with wine staging TR2013 runs faster than ported version.
    That probably depends on a card

    Yes I do, I really like win10 (close enought to gnome3 )
    No one talking about low fps, no one complain here. Dual gfx works good enought with radeon (official driver for SI/CIK)

    this film wine>native ... it's not clear what preset is in use.
    probably in native tess is on etc.

    Yeah fps is good on nVidia on fast enough card ... but in comparison to Windows again nope

    No, compiling manually is not the issue, I don't want to potentially lose a day of productivity before shipping the project. Like to keep my work-life low stress.
    I have been running manually built kernels for close on 11 years now.

    In 3 weeks it'll be 4.9-rc1 i think, for archlinux even CIK isn't enable yet, so i have to compile kernel myself. Probably you won't avoid this step

    frosth Thanks. So performance difference is a wash right now. I'll seriously have a look at it in 3 weeks.

    this is my numbers:

    I don't have any unity games so I don't know how it works, but don't expect too much.

    What do you try to say?
    CIK is supported over year, SI has working dpm since 2 weeks. It's not comparable. If I run my haswell as primary gfx and verde as secondary (like laptops do) it just doesn't work. Better use the livecd with SI support for try. it's easy and safe. And DAL has nothing to offer for SI by now.

    debianxfce do you have si gfx?, amd-staging-4.6, amd-staging-4.7, drm-next-4.9 and drm-next-4.9-wip are very close for SI support, and the last one is most update. If you have SI card and Intel gfx try it, but this setup with enabled igpu doesn't work for me.
