Desync problems on games I; d tried

[trihy]

Hi guys. Can you help me with this?

I tried some games and most desync after a few minutes. I get warning on chat window.

Most I tried are Mario kart 64 and Mario kart Wii.

Both dolphin clients has stock settings. Latest dev build.

I'm using amd gpu and my friend Nvidia one. Not sure if a render is better for this, tried vulkan, dx11, 12 all desync.

My friend is only a couple of blocks from my house. Latency is around 15 to 20ms.

Any ideas what can I do to improve this? I use direct connection.

Tried pad buffer up to 10, no changes.

What is the ping/upload/download speed of both you and your friend? You can use a website like http://speedtest.net to test this.

Are you using the transversal server or direct connect in Dolphin?

Are you both using WiFi or Ethernet into your computers?

Connection issues don't cause desyncs, as we use reliable networking so packets will never be dropped. Either the desync is being caused by mismatched dumps or there's a legitimate bug. Click on Checksum > Current game in the netplay dialog to compare your dumps, if they don't match that's likely the culprit.

Hi. Isos match checksum.

Im using direct connection. Not sure if its better to use other type of connection.

Ie on mario kart 64 chat window warns about a desync just when starting the first track. Game still work fine but lost sync some minutes later, without any additional warning.

Connection is fine, 50/10mbps on both. Ping around 20ms. Both on ethernet cable.

What wonders me, I played nestopia using kaillera or something like that and finished many games without any desync, the same day.

I Will check better the Dolphin config. Not sure if using ubershaders is better or worst.

Im using pretty much a clean Dolphin build with stock settings and copied the same folder to my friend computer. Dolphin is running on portable mode, cause both have another Dolphin for daily and local use.
