The 551 series is "just right for playing NS2"; before buying any of these, you must go through the capture specs item by item. Last updated: 2026-10-06 (in-depth rewrite)

[Spec disputes (the group's biggest gripe)]

[Positive experiences (both sides of the same user's review, Allen Lee Xbox)]

• Note how it is used: 4K HDR only runs at 30hz + p010 + frame interpolation up to 60 — accept 30-frame HDR and this is the experience you get

[Q&A] ("almost no latency, very satisfying", thanks to frame interpolation); want 2K60 HDR (NS2) → "basically perfect". Q Price reference: 1900 (purchase price at the end of last month) / 2200 (quoted price)

[Conclusion] A card aimed at streaming; gaming/capture users should choose carefully; when the two camps' claims conflict, go by the "capture spec sheet"

════════════════ 3. GC551 / GC551G2 / GC550 ════════════════ [GC551G2 (recommended tier for NS2)]

• "if you have more money go for the AVerMedia gc551g2, just right for playing ns2" "if you still want lower latency you have to go to 2000" (月光疾风)

• User case: Aya (4080 + GC551G2) — rated "a 4080 is definitely enough"; note that their "PC hasn't had its drivers updated in years" → update the drivers first

• Xuo hesitates: "is the 551g2 enough, I see people who bought the 553g2 still hesitating"

• Audio problem (ハスタンの月色): "the built-in video either freezes or there's still no sound" → troubleshooting: select the capture card in both Windows and the software; "the software has taken over the capture card, so obs can't capture anymore" (a capture card can only be occupied by one program at a time)

the capture card picture?" → the author replied "other AMD card users report it's normal" (handle it as an individual AMD card case: send the logs for troubleshooting) ("it's not a capture card problem") → when the 2K frame rate won't go up, first lower the rendering load inside Veyra

════════════════ 4. Overall buying advice ════════════════

• For 2K60 needs: a GC553G2 is enough; or the Kuhaomi 27P / Michensen T800 (half the price, 10-15ms)

• NS2 players: GC551G2 ("just right") / GC553G2 / Kuhaomi 27P all work; for VRR needs pick the G50

• General rule of thumb: before buying any AVerMedia model, first go through the "capture format table" (resolution × format × frame rate × HDR) item by item — "check it clearly before you buy" (Aitor); "the passthrough specs are useless to us" (the author) ================================================================

This update (2026-11-05)

• Support's official line: compared with the old model, the 551G2's latency hasn't been optimized (new, 10-12, relayed); an old GC551 second-hand for a bit over 100 can also do 2K60.
