去年6月，在虛幻引擎2025大會上，CDPR通過他們《巫師4》Demo讓眾人展示了虛幻5.6引擎，震驚四座。雖然CDPR後來表示這只是一個演示Demo，不代表最終遊戲，但推主NikTek認為，CDPR這種做法無疑為《巫師4》在玩家心目中設定了一個較高的心理預期。如果最終的成品達不到Demo演示中的效果，那麼《巫師4》很有可能「重蹈《電馭叛客2077》過度承諾的覆轍」。
NikTek推文：
CDPR主動將《巫師4》的技術Demo作為虛幻5引擎的展示，這意味著他們已經相應地設定了玩家對《巫師4》的期望。
如果《巫師4》的畫面和玩法與此不符，就會重蹈《電馭叛客2077》過度承諾的覆轍，我覺得會遭到一些玩家的強烈反對。。
這雖然是「技術演示，並非實際遊戲玩法」，但我很難理解，如果最終產品不會與此完全相同，那麼展示引擎的意義何在，除了宣傳遊戲之外?
《巫師4》仍在開發中，所以玩家當然期待視覺效果、地圖、動畫和角色模型等方面的變化，除此之外，《巫師4》應該包含他們在Demo演示中展示的所有功能
例如：
- 多角色動作匹配
- 肌肉變形
- 高密度植被
- 真實的NPC人群
- 一個響應迅速的世界
- 良好的性能（沒有虛幻引擎5的卡頓）
- 流暢的NPC互動和過場動畫
如果這些功能最終沒有出現在成品中，我會對CDPR感到失望，因為這似乎表明他們在《電馭叛客2077》之後並沒有吸取教訓。
The fact that CDPR willingly showed this Witcher 4 tech demo as an Unreal Engine 5 showcase means they have already set the expectations accordingly for Witcher 4. If Witcher 4 doesn't look like this or play like this, it will be the same situation of overpromising that Cyberpunk 2077 had and I feel like there's going to be some backlash. It is a "Technical Representation - Not Actual Gameplay" but I struggle to understand what was the point of flexing the engine if the final product wont be identical to this, other than hyping the game up? Witcher 4 is still in development, so of course I expect changes that are visual, map changes, animations and character models, otherwise Witcher 4 should incorporate all the features they showed in this demo like: >multi character motion matching >muscle deformation >high foliage density >realistic NPC crowds >a responsive world >good performance (no UE5 stutters) >seamless NPC interactions and cutscenes I'd be disappointed in CDPR if these features didn't make it to the final product because it would seem that they haven't learned their lesson after Cyberpunk 2077.

The release of Cyberpunk 2077 will forever be a stain on the legacy of CDPR. The only other time I’ve been that disappointed was the teasers for watchdogs 1 vs the game at release. Witcher 3 was absolutely gold.
I suspect the game will be buggy and poorly optimized at launch. Way too many AAA games launch that way these days for me to expect any less. All I hope for is a year or two after launch CDPR incorporates all or most of these features and it is a true showcase of current gen hardware. I'll buy the game whenever that is the case, not before.
We all saw the UE5 showcase demo in 2020. No UE5 game has ever looked anything close to it and no UE5 game has the features showcased in that demo. These tech demos are unrealistic and should be treated with the same level of speculation as Watch Dogs 1’s E3 demo.
