Is it possible to get 100% accuracy in a game?

That would tell me nothing about the percentage accuracy. It doesn't even give any percentages, only a CAPS2 score.

Yes, it is possible. Is it probable? No, but there must be a set of moves that the computer thinks are "best", and if you play them exactly as the computer would, then congrats, you just played 100% like a computer.

I played one. You have to have all book moves. If you have a single best, it's a 99.9

I got 100% accuracy in bullet game as the game was only of 5 moves and the person was playing very fast, leading to losing his queen and resignation. Go check my archive, there will be a game with 100% accuracy

How are we to check that your moves were accurate?
Check them against the engine since all the accuracy scores are given against the engine set on a superficial or weak search?

That doesn't tell you whether they're accurate. The engine moves with the highest evaluation can vary depending on the time allocated or even if the time allocated is the same. But in any case you don't know if the move(s) with the highest evaluation are accurate or even perfect.
Yes, I got it 2 times

That IS what I said! 
Using different wording!

How do we check moves for accuracy? Your answer - check something unrelated.
@Rifleman7 didn't suggest we could find a game with 100 CAPS2 score he said we could find a game with 100% accuracy. (Not relevant, but even the CAPS2 score can vary between reviews.)
Oh, I was using a bit of irony for emphasis. I forgot about you. Never mind.
I even gave enough information, from which anyone not feeble-minded would understand that irony was in use. I didn't even leave it to chance.
The game review "percentages" shown on chess.com are not percentages, nor displayed as such. Read the documentation.
Percentage accuracy (the percentage of accurate moves in the total number of moves) has even less connection with perfect play in general. If the version of chess played has no 50/75M rule or 3/5R rule a perfect game can have a percentage accuracy for both players as close to 0 as you please (except 0 itself).
