QSPICE Simulation Speed and Waveform Viewing Experience vs LTspice

I tested QSPICE. For the same circuit, QSPICE simulates much faster than LTspice. But the waveform viewer is less convenient to use. LTspice has direct clickable buttons for waveform controls, while QSPICE relies on right‑click menus with small, easy-to-misclick options.

With large simulation datasets, LTspice simulation is slow but waveform viewing remains smooth. QSPICE runs fast during simulation, but waveform browsing lags.

I hope QSPICE can learn from LTspice’s waveform viewer and improve further.

I guess you are Chinese. 你遇到這問題時,.qraw 的檔案通常是多大? 你的電腦有 3D 顯卡嗎?
Help 裡面有說過 waveform viewer 是 3D 顯卡優化的。
