I personally have it set to 720p, as there is no point in wasting cpu power rendering these games at 1080p, and at 1080p, a lot of shaders will slow the device down, whereas they work fine at 720p

Also, as per inside that file, you must stop the N64 and Dreamcast rendering at even 720p.

These lines are there, probably preceded with a ; so they don't take effect. That semi colon must be removed, and the lines need to be:

system.es.videomode=CEA 4 HDMI
Thats near the start

global.videomode=CEA 4 HDMI
Thats probably around line 300

n64.videomode=CEA 4 HDMI
dreamcast.videomode=CEA 4 HDMI

Those 2 will be around line 400 ish

@Chiva_Von_Chiva You can change the video mode:

BUT, I believe your TV is 4k, and there is a known bug with 4k TVs and Rpi4:

And this bug will be fixed in the next version:

Fix detection of 4k screen (# 1384)

@acris
ce sujet est CLOS
serait il possible de le mettre SOLVED, CLOSED

There is no PS2 emulator at all yet, for any system.

...allen, die ein ähnliches Problem haben rate ich dazu einen DVI auf Composite Adapter zu verwenden (wohlgemerkt nicht Composite auf DVI(!)). Die Performance lässt dadurch nicht nach und die Qualität ist auch gut bis sehr gut. Ich habe einen Adapter für unter 20 Euro und ich kann jetzt die Recalbox über den HDMI-Ausgang an die Composite-Anschlüsse eines Fernsehers anschließen und das läuft wunderbar. Allerdings bieten die Adapter leichte Unterschiede, was die Qualität angeht: Bei manchen ist das "Schwarz" als "Muster" aus grau-schwarz dargestellt, bei anderen ist es dunkelgrau. Es gibt aber auch welche, bei denen schwarz als schwarz dargestellt wird.

@ivwshane said in Raspberry Pi4 released - 3 times the performance.:

When the pi3+ came out it was said that a total rewrite of the core was required (I may not have the terminology correct). Are we looking at the same type of rewrite required or will this be something akin to recompiling the code to recognize the new hardware?

^^ This is entirely new hardware. Different CPU, Different Ram, etc. And since the Recalbox crew took like a year to make it compatible with the Pi3b+, I don't expect Recalbox to work with the Pi4 for a long, LONG, LOOOOONG time.

But when 2020 or 2021 rolls around and Recalbox does finally become compatible? I'm sure it'll be amazing!

Also this claim of the Pi4 being compatible with existing Pi products? Horsecrap! None of the existing Pi3 cases will fit, none of the existing Pi3 software will work, etc.

@anderdog to my knowledge the behaviour you mention is not possible, as we have deliberatly chosen not to update ppsspp yet because a newer version hits performance. It must be something else.

@substring said in Cluster computing for better performance:

ll, emulation is mainly monothreaded

ah well it is what it is, thank you for the quick reply

@tony-amprou said in Performance Core 2 Duo:

En test sur l’émulateur de genesis même Sonic ne semble pas fluide.

Le GPU ne devrait pas faire de différence sur ce type de jeu, après tu ne donnes aucune précision sur l'émulateur utilisé. Le CPU pourrait également avoir une basse fréquence, voire être en mode "powersave" (c'est un portable ?)

@profknt Kannst testen vielleicht mit Sandisk karte ? Manche SD karten machen einfach Probleme. Versuch bitte mit Sandisk karte. Habe keine wie von dir beschriebene Probleme bei mir.

Issue solved 🙂 check this thread https://forum.recalbox.com/topic/11249/performance-issues-after-update-rpi3/3
