SysCubes: a ready replay control
Enable Replay before playing and press Alt+S after the moment. The same overlay holds app volume, music and hardware readings.
SysCubes vs OBS Studio
OBS Studio can do almost anything with video, but saving a short clip means setting up a source, the Replay Buffer and a hotkey. SysCubes has a ready replay control next to app volume and hardware readings. Compare what each one needs and what it gives you.
In OBS you add a game source, turn on the Replay Buffer in Output settings, assign a save key and start the buffer each session. SysCubes has a Replay control with a 30-second default (5-40 seconds) and saves with Alt+S in new game profiles. Quality is one preset choice, from 720p to 4K.
Choose your priority to see whether a ready replay control or a full production tool fits.
Quick answer
SysCubes suits players who want to save the last 5-40 seconds with one key, with app volume and temperatures in the same overlay and no scenes to build first. OBS Studio is built for streaming, custom scenes, adjustable output and separate audio tracks. Run one replay recorder at a time.
Design Philosophy
Enable Replay before playing and press Alt+S after the moment. The same overlay holds app volume, music and hardware readings.
Scenes, webcams, streaming, adjustable output and separate audio tracks. More control, with more setup before the first clip.
Both encode video while their replay is on. Compare the same game scene with each tool, one at a time, to see what your PC sustains.

Compare setup, audio, output and what else each tool does.
| Capability | SysCubes | OBS Studio |
|---|---|---|
| Replay setup | Enable Replay in Screenshot & Record; 30 seconds by default. | Add a game source, turn on Replay Buffer, set its length and a save key, then start it each session. |
| Replay length | 5-40 seconds. | Set by you; longer buffers use more memory. |
| Output settings | Quality presets from 720p to 4K at 30 or 60 fps; automatic bitrate. | Resolution, frame rate, encoder and bitrate are all adjustable. |
| Audio in the clip | Game sound filtered to the game, so other apps stay out; microphone when turned on. | Any app or device as a source, each on its own track if you want. |
| In-game overlay | Widgets over a supported game, with click-through lock. | No in-game overlay; runs in its own window. |
| Volume mixer for playback | Per-app sliders for game, Discord and music in the overlay. | Mixer for recording sources, not for what you hear. |
| Livestreaming | Built for clips rather than streaming. | Yes, to Twitch, YouTube and other services. |
| Cost | Free with ads, via Overwolf. | Free and open source. |
Setup
In OBS Studio, you add a Game Capture source, open Settings, turn on Replay Buffer under Output and set its length, assign a Save Replay key under Hotkeys, then select Start Replay Buffer before each session.
In SysCubes, you select Enable Replay in Screenshot & Record before playing and press Alt+S after the moment. Quality is one preset choice, from 720p to 4K, with the bitrate set automatically.
Audio
OBS Studio records sources: with Application Audio Capture you can record the game and Discord separately and assign each to its own track, then rebalance them in an editor.
SysCubes records game sound filtered to the game, plus your microphone when you turn it on in Capture settings. Its volume mixer changes what you hear from the game, Discord and music while you play. To plan a recording that includes a Discord call, follow the game and Discord audio guide.
Summary
Choose SysCubes if you want to save 5-40 second clips with one key, with app volume and hardware readings in the same overlay.
Choose OBS Studio if you stream, need scenes or a webcam, want to fine-tune the encoder and bitrate, or need separate audio tracks.

Your questions, answered
Choose SysCubes when you mainly want to save short gameplay moments of 5 to 40 seconds with a ready replay control, next to app volume and hardware readings. Choose OBS Studio when you stream, need custom scenes or webcams, or need separate audio tracks to edit later.
Yes. SysCubes Replay keeps the last 5 to 40 seconds, 30 by default. Enable it before playing, then press Alt+S in new game profiles to save. Unlike the OBS Replay Buffer, it needs no scene or output setup: pick a Recording quality preset from 720p to 4K, and the bitrate is set automatically.
SysCubes is built for saving clips rather than live broadcasting. If you stream, keep OBS for the broadcast and use SysCubes for quick replays and in-game audio controls, with one replay recorder running at a time.
It depends on your settings, encoder, game and what else is running. Both encode video while their replay is on. Compare the same game scene with each tool active, one at a time, and keep the one whose gameplay and saved clips you prefer.
With OBS, yes: its Application Audio Capture source can capture Discord and the game separately, and each source can go on its own track. SysCubes records clean game sound, filtered to the game, plus your microphone when you turn it on, so other apps stay out of the clip. Its volume mixer lets you balance the game, Discord and music you hear while you play.
Both tools save with a keyboard shortcut while you play. In SysCubes, Alt+S saves the replay in new game profiles; in OBS, you assign a Save Replay key in Settings under Hotkeys.
Yes. SysCubes is a free, ad-supported Windows app available via Overwolf. OBS Studio is free and open source.
