Problems with video cards. Screen frequency refresh. Terminal speed.
Using Dell Wyse 7020 thin clients with Win7 embedded installed. When connecting via RDP client in Win7, it connects with RemoteFX and videos play fine in Youtube and other sites. When booting with WTWare, the client connects with the GFX codec (3 tile) and either plays the same videos at either a much lower framerate or very heavy compression.
