Q: We’re experiencing performance issues with Microsoft Teams in our Parallels Remote Application Server (RAS) environment. Users are complaining about poor audio/video quality and sluggish performance. What’s the best approach to optimize Teams for our on-premises RAS deployment? Scenario: We’re deploying Microsoft Teams across our Parallels RAS infrastructure. Half our session hosts have NVIDIA RTX A4000 cards, while the other half are CPU-only. How should we approach Teams optimization differently for each scenario, and what architecture considerations should we account for?
Architecture Foundation
When deploying Teams in a Parallels RAS environment, the key is understanding that you’re dealing with a multi-layered virtualization stack. Teams needs to efficiently traverse from the endpoint device through the RAS infrastructure to the hosted session, then back again—all while maintaining real-time performance for media workloads.
The presence of GPU hardware fundamentally changes how Teams processes media workloads in your RAS environment. Here’s what you need to architect for:
GPU-Enabled Hosts:
CPU-Only Hosts:
Scenario 1: GPU-Enabled RAS Hosts (NVIDIA RTX A4000)
Architecture Considerations
With GPU acceleration, your Teams deployment can handle significantly higher concurrent video sessions. Plan for:
Group Policy Configuration
GPU-Specific Teams Settings:
HKLM\SOFTWARE\Microsoft\Teams\IsVirtualDesktopOptimized = 1 (DWORD)
HKLM\SOFTWARE\Microsoft\Teams\DisableHWAcceleration = 0 (DWORD)
HKLM\SOFTWARE\Microsoft\Teams\DisableGpuAcceleration = 0 (DWORD)
RAS Multimedia Policies:
Resource Allocation
GPU Memory Management:
System Resources:
Scenario 2: CPU-Only RAS Hosts
Architecture Considerations
Without GPU acceleration, focus on CPU optimization and more conservative scaling:
Group Policy Configuration
CPU-Optimized Teams Settings:
HKLM\SOFTWARE\Microsoft\Teams\IsVirtualDesktopOptimized = 1 (DWORD)
HKLM\SOFTWARE\Microsoft\Teams\DisableHWAcceleration = 1 (DWORD)
HKLM\SOFTWARE\Microsoft\Teams\DisableGpuAcceleration = 1 (DWORD)
Performance Optimization Policies:
Resource Allocation
CPU Management:
Memory Allocation:
QoS Strategy: Universal Best Practices
Regardless of GPU presence, implement consistent QoS policies:
Traffic Classification:
Audio (DSCP 46):
├── Guaranteed: 100 kbps per session
├── Latency: <150ms
└── Loss tolerance: <0.1%
Video (DSCP 34):
├── GPU hosts: Up to 2.5 Mbps per session
├── CPU hosts: Up to 1.8 Mbps per session
├── Latency: <400ms
└── Burst allowance: 2x guaranteed rate

Your dual-configuration approach requires thoughtful architecture but delivers significant benefits. GPU hosts can support 60-70% more concurrent video users while providing better quality. CPU hosts, when properly optimized, still deliver solid performance for mixed workloads.
Key Success Factors:
The investment in GPU acceleration typically pays for itself through improved user density and experience—just ensure your architecture takes full advantage of both configurations.
