rtx5000 ADA vs rtx6000 ADA

[domi2205]

Description

Riscontro il problema che su una macchina con rtx5000 faccio 60hz di frequenza di simulazione mentre sulla rtx6000 ne faccio 30.

Isaac Sim version

5.1.0

Operating System (OS)

22.04

GPU Name

RTX 5000ADA AND RTX6000ADA

GPU Driver and CUDA versions

580.95.05 per la 6000 e 580.142 sulla 5000

Logs

Riscontro il problema che su una macchina con rtx5000 faccio 60hz di frequenza di simulazione mentre sulla rtx6000 ne faccio 30.
Ho creato tutto sulla rtx5000, esportato il docker e reinstallato sulla 6000.

Additional information

Inoltre, sto lavorando per acquisizioni della scena con camere rgb e le invio via ros a un container che ascolta, sulla 5000 vengono ricevuti a circa gli stessi fps con cui acquisisce in simulazione, (simulazione gira a 50hz e io per scelta acquisisco a 30) , sulla 6000 non salgo sopra i 10fps, a volte fa anche 0

Hi @domi2205, to better assist you, could you please post in English?

To summarize your issue:

• RTX 5000 Ada (driver 580.142): simulation runs at 60 Hz, ROS camera publishes at expected rates (~30 fps)
• RTX 6000 Ada (driver 580.95.05): simulation drops to 30 Hz, ROS camera publishes at only ~10 fps or lower

This is counterintuitive since the RTX 6000 Ada is a more powerful GPU. A few things to investigate:

1. Driver Version Mismatch

You have different driver versions on the two machines (580.142 vs 580.95.05). While both are in the R580 branch, try installing the same driver version on both machines to rule out driver differences.

2. Multi-GPU Configuration

If the RTX 6000 machine has multiple GPUs or a different PCIe configuration, try disabling multi-GPU rendering.

3. CPU Governor Settings

Check the CPU governor on the RTX 6000 machine. A slower CPU governor can bottleneck simulation performance even with a powerful GPU. See CPU Governor Settings
(https://docs.isaacsim.omniverse.nvidia.com/latest/reference_material/sim_performance_optimization_handbook.html#cpu-governor-settings-on-linux).

4. Docker Container Differences

Since you exported the Docker container from the RTX 5000 machine, there may be hardware-specific settings baked in. Try:

• Running with --reset-user to clear any cached settings
• Installing Isaac Sim fresh on the RTX 6000 machine instead of using the exported container

5. Run the Benchmark

Run the official benchmark (https://docs.isaacsim.omniverse.nvidia.com/latest/reference_material/benchmarks.html#measuring-kpis-on-local-hardware) on both machines and share the results. This helps isolate whether the issue is with rendering, physics, or ROS communication.

If still seeing abnormal performance, capture a trace of the slowdown (~10 seconds worth) using the Tracy profiler and share here. That can help identify what specifically on this system seems to be causing the slowdown. Docs here
