The new Raspberry Pi 4 is here!!

retropi19

i dont have a raspberry pi 3b+
which one you have for the Rpi4?

Bearwynn

@retropi19 the one that I linked is the one that I have for the Raspberry Pi 4

Bearwynn

@quicksilver I have tested this now and you're correct, anything above 1750Mhz and the raspberry pi 4 will underclock itself to exactly 1Ghz.

Interestingly, it also underclocks the minimum clock speed to about 300Mhz, down from 600Mhz

quicksilver

@Bearwynn I think I read somewhere that there will be a firmware update to change that limit. Perhaps you could try updating to see if it's already available?

Brunnis

Spent an hour or so tonight and now have RetroArch (with the XMB interface) running on my Pi 4 on Raspbian Buster Lite (i.e. I'm not running it from the Raspbian desktop). I also built snes9x2010 as a test (this required modifying the makefile slightly) and ran SMW2: Yoshi's Island as a test. The spinning island scene runs at 148 FPS. No time to test anything else yet.

Ohh, I noticed one issue: There is major tearing and some stuttering in both the XMB GUI and during gameplay. Something's not working as it should when it comes to updating the display. Maybe a GPU driver issue?

Bearwynn

@quicksilver I'll keep my eyes and ears peeled. I can't see anything on the official forums about it though.

Is the Pi 4 4GB even out yet?
I can't seem to find it in stock anywhere

Also, do you recommend their power supply, or would any USB-C Work.
I see Canakit has a set that comes with an adapter, which is why I asked.

(Same question for the 3B, is the Official power supply any better than the other brands?)

Yes, it was sold out first since probably the fraction of 4G produced was smaller than 2GB + 1GGB combined.

Can't say, but I've seen some tests on their forums with various power adapters with various degrees of success.

(Same question for the 3B, is the Official power supply any better than the other brands?)

It is better.

try updating the firmware? i have see a couple of similar sounding issues in the firmware repo over the last weeks

Brunnis

@dankcushions I thought I had done that on this image, but I'll double check. Thanks.

Barcrest

I see that there is new firmware in test that helps lower the temps without performance suffering. It will be nice when that gets released.

Updated the firmware yesterday and it indeed seems to have solved that issue. However, setting video_max_swapchain_images=2 in order to reduce input lag makes the issue return. The performance also plummets (150 FPS -> 57 FPS in Yoshi's Island). This setting is performance intensive, but shouldn't cause such a severe degradation. Something's probably still not right with the GPU driver.

Barcrest

Here are some emulators being tested on the pi4

Saturn doesn't look good at the moment.

dankcushions

@Barcrest yabause-sanshiro libretro core clearly not running on the hardware properly. why even test on that when standalone exists? i do wish eta-prime would chill out on his quest for views and just wait until anyone who knows what they're doing has done the work for him. retroarch was reporting ARMv7, for a start...

retropi19

@Brunnis they revert the firmware update probably they found the performance drop

Bearwynn

@dankcushions he did an overclocking video and it was so bad and obviously for views.

He did over_voltage=2 and then two lines later did over_voltage=4, thus overwriting the first one.

quicksilver

@Bearwynn and in the videos I saw (dont know about his latest) he says nothing about proper stability testing. A lot of people out there just copy paste what they see him do and then wonder why their pi is freezing/crashing all the time.

jrb555

@quicksilver He reviewed the GPi case, and everyone went and bought it. Then some users started complaining about an audio noise issue.
Turns out, Lon.TV reviewed the case too at about the same time as ETA Prime, but he really went into detail about that issue and I just dodged a freaking bullet thanks to that.

@jrb555 You know, I have become a stickler for reading reviews for this very reason. I've wasted some cash on taking someone's word for it. A lot of the '1 or 2 Star' reviews are the purchaser's faults or "1 Star because the green seems more pine green than army green" reviews but you'll catch a consistency among them if you read enough and there is a problem.

@retropi19
Upgrade Retropie to Buster does not work on pi4
Needs a clean buster base to boot and then same can be backwards compatible
