Recording games at 4K on GTX 770

[ManiKz]

So my friend has a bit of a dilemma with recording games at 4K (3840 x 2160) using his Nvidia GTX 770.

He wants to record at 4K 60fps with little to none performance hit.

Geforce ShadowPlay wont record higher than 1440p 30fps and OBS will record 1440p at 60fps, 4K at 30fps and 48fps but refuses to record 4K 60fps.

He's tried numerous capturing software from the likes of Bandicam, Camtasia and Mirrilis Action which have all failed at doing the job with poor recordings which suffer from frame drops or just not recording at all.

His PC specifications are Intel i5 4590, 16GB DDR3 1866Mhz and Nvidia GTX 770.

If you need any more details for this issue then feel free to ask and any help is appreciated.

If this is in the wrong section, mods/admins feel free to move it to the correct section.

If you want to capture 4k in 60fps you'll need at least a Blackmagic Design Decklink, about $565+ (USD), or a Matrox Mojito, about $2000 (USD)
