When shopping for a capture card for Helldivers 2, focus on three core specs: capture resolution, frame rate, and passthrough capability.
Capture specs matter most. You want at least 1080p60 for clean gameplay footage. If you're streaming, 1080p60 is the standard—it's easier on your upload bandwidth than 4K, and viewers on Twitch and YouTube see it clearly. Some cards offer 4K capture, but that demands more CPU and storage. For Helldivers 2's fast combat, 60fps is the minimum; anything less feels sluggish.
Passthrough is your friend. This feature lets you monitor your game on a TV or external display while capturing, with minimal latency. It's essential if you're streaming live—you need to see what's happening in real-time, not rely on a delayed preview. Cards with HDMI loop-out or passthrough cost a bit more but prevent the "blind streaming" nightmare.
Connection type shapes your workflow. USB 3.0 external cards are plug-and-play; just connect to your PC or Mac and launch OBS. USB-C options are faster and cleaner for newer machines. PCIe internal cards require installation but offer the lowest latency and highest stability—ideal if you're building a dedicated streaming PC.
Watch for latency specs. Ultra-low latency (under 100ms) matters for competitive gameplay. Helldivers 2 is fast; if your capture card adds half a second of delay, you'll struggle to react. Check reviews for real-world latency, not just marketing claims.
Budget vs. features. Sub-$30 cards work fine for 1080p60 recording and streaming. Mid-range ($60–$100) adds 4K passthrough and better build quality. Premium cards ($150+) deliver 4K60 capture, 1440p120, or even 1080p240 for ultra-smooth playback. Pick based on your actual needs—don't overspend on 4K if your stream maxes out at 1080p.
