Remote work didn’t just change how teams collaborate: it transformed how game testing gets done.
Today’s QA teams are global, developers work across time zones, and playtests happen far beyond a single studio. That makes screen sharing no longer optional, but essential. The challenge is that most remote tools weren’t built for real gameplay. They lag, drop frames, and blur the details QA teams rely on.
DeskIn is different. It’s engineered for high-FPS visuals, ultra-low latency, and accurate gameplay feedback, making it a modern screen-sharing solution built specifically for remote game testing and remote gameplay.
Let’s break down why DeskIn is quickly becoming the best screen-sharing tool for game developers, and why tools like AnyDesk, TeamViewer, and even Parsec fall short for serious QA work.

Real Use Cases in Game QA & Development, Why Need a Screen Sharing Tool?
Remote screen sharing has moved from a "nice-to-have" to a critical, indispensable tool in modern game Quality Assurance (QA). Its adoption is driven by fundamental shifts in how games are developed, tested, and collaborated on.
Here’s a breakdown of why it's now essential:
Real-time bug reproduction
QA shares live gameplay while developers observe inputs and system behavior, allowing issues to be reproduced and fixed immediately: no back-and-forth recordings required.VFX and visual review
Teams review lighting, shaders, and effects with crisp color accuracy during screen sharing for game testing, without compression hiding defects.Remote prototype playtesting
Testers play early builds remotely, enabling fast feedback without large downloads or complex setup using remote game testing software.Cross-play testing (mobile & PC)
Teams can test mobile and PC gameplay side by side, mirroring mobile screens to desktop while validating controls, UI behavior, and performance across platforms, an essential use case for remote QA tools.Animation timing review
Animation teams benefit from high-FPS streaming to review movement and timing frame by frame. Subtle issues in transitions, hit reactions, or camera motion are easier to spot when playback is smooth and accurate.Multiplayer latency testing
QA can conduct latency and synchronization tests while developers watch live sessions. This helps teams identify network-related issues faster using effective remote dev tools.Secure external QA access
External QA partners can securely access builds and testing environments through DeskIn, making collaboration smoother while keeping pre-release content protected.
Modern Tools Elevating the Practice
Today’s game testing workflows rely on tools that go far beyond simple screen viewing solutions like Zoom. Modern remote platforms such as DeskIn, AnyDesk, TeamViewer, and Parsec introduce capabilities specifically designed to support game QA.
Choosing the right tool comes down to which features best support real-time testing and collaboration, including:
High frame rate and low latency — critical for spotting fast-paced visual bugs and timing-sensitive issues.
Remote input control — allows developers to take over instantly and test hypotheses without lengthy explanations.
Built-in file transfer — enables quick delivery of new builds, patches, or configuration files.
Real-time screen mirroring — makes it easy to share bug reproduction steps for immediate analysis.
Audio calls and whiteboard tools — support clear communication and visual guidance without relying on third-party apps.
Together, these features transform remote sessions into efficient, collaborative QA environments, bringing teams closer to the feel of in-studio testing.
Which Screen Sharing Tool is Best for Game QA
Choosing the right screen sharing tool can make the difference between a lengthy, ambiguous bug report and a swift, precise fix.
For Game QA, the ideal solution must go beyond basic screen viewing; it needs to deliver high visual fidelity, ultra-low latency, cross-platform compatibility, and interactive control to keep up with the real-time, detail-sensitive nature of game testing.
Below, we break down what to look for and compare top contenders shaping how modern game teams test.

AnyDesk
AnyDesk is primarily designed for IT support and remote troubleshooting, which limits its effectiveness for screen sharing for game testing.
Cross-platform compatibility: Supports Windows, macOS, Linux (Ubuntu, Debian, RHEL, SUSE, Mint), Android, iOS/iPadOS, plus specialized platforms like Raspberry Pi and ChromeOS.
Image quality & FPS: Supports up to 60 FPS, which is often insufficient for reviewing fast animations, camera motion, or combat flow.
Latency: Acceptable for support tasks (typically around 80–120ms), but inconsistent for timing-sensitive gameplay such as combat, physics interactions, or input validation.
Network stability: Generally stable for light workloads, but performance degrades under GPU-heavy scenes.
External device adaptation: Does not support game controllers, limiting accurate input and control testing.
Interactive features: Basic remote control; lacks advanced collaboration features tailored for QA.
File transfer speed: Supported, but slower and less integrated into rapid QA iteration cycles.

Parsec
Parsec comes closer to gaming needs, but still has gaps for structured QA and dev pipelines.
Cross-platform compatibility: Strong on Windows and macOS; mobile and broader cross-system workflows are more limited.
Image quality & FPS: Capable of high FPS (Max at 4K60FPS) streaming, but visual quality and color fidelity depend heavily on manual configuration.
Latency: Low latency (50-80 ms) when well-tuned, but performance varies based on network setup and user expertise.
Network stability: Performs well in controlled environments, but requires tuning for consistent results across teams.
External device adaptation: Supports controllers, but setup can vary and may require additional configuration.
Interactive features: Focused on gameplay streaming rather than full QA collaboration (logs, builds, multi-device testing).
File transfer speed: Does not support built-in file transfer, requiring third-party tools for builds and logs.
