The 23-year-old only moved north from Cardiff on a six-month loan deal last week but shook off his long spell of idleness to help County claim a 3-3 draw against Partick at Firhill.
His last appearance for the Bluebirds was an FA Cup run out against Macclesfield last January but he showed no rustiness with an impressive Scottish Premiership debut against the Jags.
And former Morton midfielder Tidser, another new Derek Adams recruit after moving north from Rotherham on loan until the end of the season, says Kiss will only improve as his fitness returns.
"You can see Filip is a good player," he said. "I've trained with him this week and you can see that. You don't come up here from Cardiff if you are a bad player.
"We're delighted to have him and hopefully he can keep producing performances like that.
"He scored two quality goals and that's what you get when you bring in boys from higher levels. You expect them to produce the goods like that.
"He's not played for almost a year and after 10 minutes he told me he was feeling his calf, so for him to put on a performance like that is incredible. You just wonder what he will be like when he's fully fit."
County were sluggish in the opening 20 minutes but took the lead as Kiss finished off a fine team move with a low finish that he caressed past Scott Fox.
But Thistle soon clicked into gear as they went in search of their first home league win since April.
New striker Lyle Taylor struck twice for former club Falkirk at Firhill last season and kept up his 100 per cent record as he made his home bow as a Jags player.
First he drilled a deflected strike past Michael Fraser on 28 minutes after Stephen O'Donnell and Stevie Lawless broke quickly up field and then netted another 10 minutes later as he headed home at the near-post from an Aaron Taylor-Sinclair cross.
Lawless stabbed home a third a minute after the break and that should have been enough to confirm victory.
But as the Jags got jittery, Ben Gordon was allowed to hit back straight away after Taylor-Sinclair was forced to clear off his own goal-line from Richie Brittain's header, while Kiss kept his composure to slot home the equaliser with a quarter of an hour left after the Staggies skipper sent him through on goal.
County finished with 10 men after sub Stuart Kettlewell received a red card for a late lunge on Ross Forbes just 60 seconds after replacing Tidser.
But Thistle had nothing left in the tank and settled for yet another missed opportunity at home.
Boss Alan Archibald admitted after the match that his side may now have a mental block when it comes to playing in front of their own fans but Taylor believes a Firhill win is just around the corner.
"I don't sense any nervousness in our squad," he said. "The boys have still got the same kind of mindset as they had last year when I played against them when I was at Falkirk. There is positivity in that dressing room.
"I don't think the home win is too far away. I don't think another home win is to far away, whether it's at home or away. We all have that confidence.
"There were not many times during the game where I felt our fans were anxious. Even when County equalised, the fans got behind us even more. That's what we need and I thought they were brilliant.
"If they can be as good as that for the rest of the season I'm hoping we can match their commitment and keep the club in the Premiership."
